Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to service the lower front light. This is the side marker light, the signal light, as well as your daytime driving lights. We'll show you both changing the bulbs, as well as if you want to replace it with a whole new assembly from 1A Auto. If you go for it, a new set of lights on the front end of your truck will take miles off, make it look a whole lot better, and help you see better at night. You won't need any tools for this. You may want a flat blade screwdriver.

Open up the hood by pulling the lever here. Reach under the center of the hood, you'll see a little lever right here. Push it towards the center of the truck and lift up.

The headlights are pretty easy. There's actually a little lock bar right here. Pull it up out of the clip. You might have to work it back and forth as you pull it towards the center of the truck. This pulls right out, and then your headlight tilts back and out. Right in behind, your headlights are connected. You don't have to have the battery disconnected. As long as the truck's off, there's no power going through here. Just pull back on these tabs and push off the connectors, and your whole assembly comes out.

Now if you're just looking to change the amber signal bulb, it's right here. There's a little tab. Press down, twist counterclockwise, and that comes out. Twist back in to lock it. Do the same thing, here, with your driving light: on the little tab, push down, twist counterclockwise, and that can come out. I've pulled that out for right now.

If you want to remove the whole assembly, just push the little tab right here. Push this tab towards the outside of the truck. Most of the time I'm able to push this tab just with my fingers and pull the light out, but it's possible you may want to use a flat blade screwdriver, here, to help you push on the tab, and then even twist it a little bit to help pry that tab from the body of the truck. The whole thing comes out. Disconnect here. Your marker light is down here, just twist it counterclockwise, pull that out, and the whole marker comes out.

Just to show you, here, on these bulbs, I just pull right out of their sockets like that, and they go back in.

Reinstall the new light from 1A Auto. It's going to go in just like the original. Put your marker in first. Push through the signal bulb, and your other bulb. There's a tab right here on the inside, make sure it goes into the radiator support. Then just watch this tab go right in, and it snaps right in place.

f you had some damage or your lights are clouded or faded, the new light from 1A Auto is going to go in there just like the original. It plugs in. The bulbs plug in just like the originals. On the bottom, there are two tabs that go into slots here, so you kind of feed it in behind the grill, and peek back in there so you can see those tabs going into the right spots. Once they're in, then, line it up right here. Push it back in, put the pin in and through, and just push it through until it locks down in place again. Then, for the new light, peel off the plastic covering.

To open the hood on this 2005 Avalanche, open your door. Pull the release. The secondary release is actually under the emblem here. Push it to this side, and lift the hood up. To change this headlamp, you first have to remove the turn signal lamp. Reach down, push this tab in. Push this tab in right here, pull it out. Now, we're going to pull the headlamp away from the grill, off the tabs that it's mounted on. Push this in. Turn it counterclockwise to remove the bulb and socket. Turn the marker light bulb counterclockwise to remove it.

There are two pins, L-shaped pins, one here and one here. I'm going to unlock those to remove the light. I'm going to use a flat-bladed screwdriver to pop it out. Pull it straight out. Same thing over here. Pull it straight up and out. Put those aside. Headlamp is free. I'm going to unlock the connector on the lamp on the bulb and push it down. Pull it off. I'm going to undo the other side. I'm going to pull the clip or the lock on it away from the headlamp, and I'm going to push down on the connector at the same time to pull it off. Then, you can lift the light up and slide it out.

Here's our old yellow and discolored headlamp. It's all pitted from going down the road. You can't really see that well out of this. This is our new one from 1aauto.com, perfectly clear. You're going to have great night vision with this. It comes with two new bulbs, and look at the old one. It has the same style of mounting and the same shape. It'll fit great and look great.

I'm going to take our new head lamp. I'm going to feed that up like that. That has the adjustment for it. I'm going to plug in our connectors. Place it into the little mounting area. We'll reinstall these L-pins. This one will slide down just like that, and I can move it around a little bit to line it up. You flip it over and lock it in. Same thing with the other side. You need to wiggle the headlamp a little bit to get it in there. You want to flip it over and lock it. The headlamp is installed.

Now, reinstall your turn signal lamp. Turn this clockwise to lock it. Install the side marker bulb. Turn it clockwise to lock it. Put these tabs into the radiator support. Push this up and in. If you need to adjust the aim of the headlamp, you can turn this screw in or out.

This is a basic tutorial on how to aim the headlights on your vehicle. Find the axis of your headlights. This is usually indicated with a small dot or the headlight bulb size on the lens. If not, it's the actual center point of your headlight bulb. Transfer this mark to a vertical wall with a preferably dark color that'll allow you to back up 25 feet. Pull up and find the center line of your vehicle, as well as the center line of your headlight axis.

Mark the wall with the height of the headlights and a straight line going across at that axis height. Back your vehicle up 25 feet from the wall to the front edge of your vehicle's headlights. Turn your headlights on, and locate the adjusting screw, usually on the back side of your headlights. You'll want to rotate this until the passenger hot spot or focus of the beam is approximately two inches below the line and the driver's side is four inches below the line. We change the heights on each side so you can still get a good beam to the off side of the road on the passenger's side and have the driver's side low enough to not blind oncoming traffic.

One of the first things you're going to want to do is make sure that your hood is up. Once it's up, if you were to look right along here, you're going to see this bar. Go ahead and grab on it, flip it up, and then draw it away. We'll set that aside. Just go ahead and grab on to that headlamp assembly. Give it a little wiggle. It's going to break free. Bring it up. Then you should be able to see the backside.

Now, if you were to look at the backside, you're going to be able to see your high beam assembly. Go ahead and pull out that pigtail. Take a peek at the bulb just to make sure it's in good condition. We're going to carefully set this aside. Do the same right here. Twist that out with the headlight bulb. Take a look. Make sure it's in good condition. These look great, and there's our headlamp assembly.

Next, what we're going to do, is we're going to take the bulbs off of here. Just take a small pocket screwdriver, kind of weasel it inside there, separate those prongs, and then draw the bulb off. This one is the high beam, and this one will be the low beam. Now, we're just going to take out the headlamp on the other side of the vehicle. The next thing we're going to do is remove this top plastic area here. You're going to see a whole bunch of push clips coming across the top. Go ahead and draw out the center, and then draw out the outer portion.

There's the center. There's the outer portion. Do the same to all. Those push clips are out. Let's go ahead and get this off of here. Maybe time to get the grille off of here. To do that, if you were to look along the backside, you're going to see these little tabs that, kind of, hold it in. There's a couple of ways you can get these off. You can use a nice screwdriver, press down on the tab, and then just draw it away. Or if you're dealing with one of these sideways clips like this one, it might be a little bit harder with a screwdriver. So, you could also use some needle nose pliers, grab right onto it, and then draw it away.

If you were to look down along the bottom, there should be an area that's secured with one of these tabs as well. It's a little bit smaller. Go ahead and get that off of there, and then we'll do the same down the line. Let's go ahead and take this right off of here. The next thing we're going to do is get this off of here. To do that, there's a little tab right there. Go ahead and squeeze on that, and then draw this away. Give it a nice squeeze. Throw it away. For these, you press in right there. That's the lock, and then you twist it counterclockwise. They come right off. I always take a peek at the bulbs. Both of these look good.

Let's check this one. That looks good as well. Now, the next thing we're going to need to do, to get this off of here is, of course, to remove all the mounting bolts. You're going to notice that there's several. There's going to be some 10-millimeter bolts, and there's also going to be some T25 bolts. With that said, let's get started. There's going to be one straight down and under here. Real quick.

There should be one right here. This one is broken. Another one there, move it around. Another one, another one, that leads us to the T25 Torx bits. And grab on to that. Be careful for any bulbs that might be attached, or going through anything. You don't want to damage them, of course. Go ahead and remove your unit. Okay, friends, so it's time for an install.

Let's go ahead and grab our piece. We have our assemblies back here, the pigtails. You want to make sure everything is in good order. This right here is going to go up to your high beams, so it's going to come up along the top. This is going to come through one of the lower holes. And then, of course, we have this. This is going to go through the lower hole as well. We can set all these aside. Go ahead and grab it. Bring it down to approximately where it's going to go. Go ahead and put your pigtail through here, right down through that hole.

We've got these ones. You have that one right there, the marker as well. And then you'll have this one for the headlight. We're going to go ahead and put that up and through here. This looks great. We'll leave it like that. Now, we're just going to take our assembly. Line it up with where it needs to go. Make sure you don't have your hood cables, so it's going to get pinched or crimped in any way. Let's find that hole. There it is. Go ahead and start in one of those bolts.

We remember that this one right here was one of the Torx bits, and this one right here was also one of the Torx bits. After that, go ahead and put in all the rest of those 10-millimeter-headed bolts. Now, it's going to be time to go ahead and snug these up. Okay. As I'm tightening things up, I just like to, kind of, grab onto stuff and just make sure that I'm not crimping anything. The last thing you want to do is pinch one of these wires between the plastic here and the plastic behind it. You could, of course, potentially cause some major damage.

Now, we'll just snug up the rest. So, now it's going to be time to get this installed. Go ahead and turn it backwards. Make sure you grab your three wiring harnesses here. You have your little one for the marker. You have this one right here. It's going to go in the center for the directional, and this one right here. Get our little running light. Click it in. Put your little tab down and behind there, and then go ahead and press this in. Just make sure that you don't have any wiring harnesses behind there. Latches in. Give it a nice tug.

Now, it's going to be time to get the grille on here. Just carefully bring it up. You want to be careful you're clear for all your paint. Line up the pitons. Put them right in. Do the same for the other side. So, now it's going to be time to get our bulbs back on here. You want to make sure that you have your high beam back inside the high beam socket. Click it in. Give it a tug. Set it down. Go ahead and attach that headlamp assembly or headlamp bulb. That looks good. Give it a tug.

Now, we're going to put these back into the assembly, like this. There it is. This one, push it in. Twist it. Now, I'm just going to carefully bring this around the backside of the grille right here. Slide it down. There we go. I might just have to push down a little bit to line up our little side prong there. It's going to be time to get our pin in here. Just go ahead and line up the holes. Slide it through. There we are. Go ahead and flip that and lock it right into the slot just like that.

Be time to get our plastic cover back over the grille here. Just go ahead and lay it down. Line up all your holes. Take our little push clips, and you can start wherever you want. Just start dropping them right in there. Go outside first and then press in the center.

So, the next thing we need to do is test those lights. We want to make sure everything works as it should. That's great.

One of the first things you need to do is pop your hood. Once you've done that, go ahead and grab onto this right here. Flip it up. Go ahead and draw it away. You might have to tilt it down to get it underneath there. Grab your headlamp assembly. Carefully pull it away. And then, if you were to look at the back, you're gonna see pigtails for the headlamps. Go ahead and grab that. Turn it counterclockwise. Carefully remove it. Do the same to the other one.

Now, it's gonna be time to install the headlamp. Go ahead and grab these bulbs. Start them. Line them up. Twist it. Lock it in. Do the same to the other. Okay. Now, we're just gonna come around the backside of the grille here just like this. Come up and over that. And then rest this right in. This should like up along there. And then, this should line up right down here. Now, we're gonna get our pin in here. It's a good idea just to clean it up if you can. Get off any of the rust that might be on it. Get it close to where I want it. Now, I'm just gonna bring the headlamp over. Squeeze this in. Bring it right on through. Line it up with this one. Flip this over.

All right. So now, it's gonna be time to test these lights. We got our headlights on. We got some high beams. Check that directional. Make sure it works. Perfect. We're sure that the lights all work. You'd want to just adjust the alignment of your headlamps. If you were to turn this to the left, it's gonna bring the beam up. If you turn it clockwise or to the right, it's gonna bring the beam down.

This is going to be a general tutorial on how to aim your brand new TRQ headlamp assemblies. Okay. So looking at your brand new TRQ headlamp assembly, you're gonna see where your low beam is, and you'll see a little dot right in the center, and that is the access point. Okay? So what we're gonna do is we're gonna mark that with an erasable marker just so it's easier to see. Next, what we need to do is measure from the level ground up to this point and take note of that measurement. Now, we're just gonna pull the car up to our wall. On our vehicle, we remember that the measurement was 28 inches for our access point. Your vehicle may be different, but that's where I'm going to put this tape. Just above that 28 inches. We'll do the same on the other side.

Okay. So let's just back the vehicle up, straight back, 25 feet from the wall. And now that we moved our vehicle 25 feet back from the wall, we're gonna start with our measurement here. That's where the headlamp center is. We're gonna go down 4 inches on the driver side. On the passenger side, we have our line here. What we need to do is go down 2 inches. To adjust the driver side, we're gonna cover our passenger side headlamp. If you look at the backside of your headlamp assembly, you're gonna see something that looks like this. This is the adjustment. Some of these headlight assemblies have one, two, or even more of them, but you should at least have one. This is how we're gonna adjust the headlight beam. Now, we're gonna lower the top part of the beam down to just below this line. When you turn the adjustment to the right it brings the beam up, and if you turn it to the left it'll bring the headlight beam down, and this is this way on most vehicles. Let's continue on to doing the passenger side. All right. We properly aligned our TRQ headlight assemblies. Okay. And on the quality TRQ headlamps for our pickup truck, the procedure's gonna be the same. You're gonna find your center dot, mark it, and then you'll measure from the level ground up to your dot.

So once your headlamps are properly adjusted, it'll be time to adjust your fog lamps. You'll notice on the driver side the focal point is all the way at the bottom right now. I would like to bring it up so it meets up with approximately the bottom of the focal point of the headlight. Some fog lamps have an adjuster, others don't. The ones that do have an adjuster, you would just turn the adjustment to the left or to the right to adjust the beam up and down to where it needs to be. Now with your TRQ headlamps and fog lamps properly aligned, you can drive down the road safely.

One of the first things you need to do is pop your hood. Once you've done that, go ahead and grab on to this right here, flip it up, go ahead and draw it away. You might have to tilt it down to get it underneath there. Grab your headlamp assembly. Carefully pull it away. And then if you were to look at the back, you're going to see the pigtails for the headlamps. Go ahead and grab that. Turn it counterclockwise. Carefully remove it. Do the same to the other one.

Now that that headlamp is out of the way, we have a clear view of what's going on down here. If you were to look right where my screwdriver is, there's a little tab. You're going to press that towards the outer portion of the fender, and then draw the assembly away. Maybe I'll try it once just so you can see. Press it. Draw it away. There we are. Go ahead and grab onto these. If you squeeze this tab right here, it should unlock, and then you can twist it. Do the same for this one, and then, of course, the marker at the end, you just twist that.

So, now we're going to get our new lamp assembly back in. Go ahead and grab this. Go ahead and turn it in. Lock it. Give it a nice wiggle. Let's get our directional bulb in here. Go ahead and twist it. Lock it in. This one, little less reach here. Lock that one in as well. Perfect. Now, when you go to install this, on the inner portion, you're going to see there's a little hookie-do. That needs to slide in over there. So, we'll go ahead and get the hookie-do into where it's supposed to sit. And then if you look right here, we're going to line this up and then carefully press it in. Make sure it's locked in. This feels great.

Now, it's going to be time to install the headlamp. Go ahead and grab these bulbs. Start them. Line them up. Twist it. Lock it in. Do the same to the other. Okay. Now we're just going to come around the backside of the grille here just like this. Come up and over that, and then rest this right in. This should line up right along there, and then this should line up right down here. Now we're going to get our pin in here. It's a good idea to just clean it up if you can get off any other rust that might be on it. Get it close to where I want it. Now I'm just going to bring the headlamp over. Squeeze this in. Bring it right on through. Line it up with this one. Flip this over. All right. So, now it's going to be time to test these lights. We've got our headlights on. We've got some high beams. Check that directional. Make sure it works. Perfect.
