Created on:
Tools used
No Tools Needed
1. Handling the Bulbs
Note: DO NOT TOUCH the bulbs- the oil from your fingers will burn into the light and foul your bulb.
Clean with rubbing alcohol and a soft cloth if the bulbs do get touched.
2. Remove the old headlight assembly
Pop the hood and secure it.
Remove the two anchor pins securing the head light assembly by twisting and pulling them up.
Remove the head light assembly.
Unplug the bulbs and harness.
3. Install the new headlight assembly
Plug in your bulbs, replacing them with new ones if necessary.
Reconnect the harness by clipping it in.
Line up the head light assembly and clip it into place.
Put the two pins back into place to secure the head light assembly.
Close the hood and enjoy your new 1A Auto headlights.
This video is brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the Internet. Hi, my name's Mike Green. I want to help you save time and money repairing your vehicle. I have 20-plus years experience restoring and repairing cars and trucks. My company, 1A Auto, sells high quality replacement parts over the Internet. In this video, I'll be showing you how to install these parts. By the end of this video, you'll know how to install them and where to get them. That's going to save you time and money. Thank you and enjoy the video.
This video, we'll be replacing the headlight on a 2004 GMC Sierra, basically the same as a '99 to '06 Sierra. It is a pretty easy process. It requires no tools. So, with that, we'll get you to it.
There are two pins that hold the headlight in right there and there, and you'll twist those out and pull them up. Then, the headlight basically comes right out. Then, once it's out, you can reach in behind and unplug the lights. They're basically just little teeth that you can kind of pull with your thumb, and they unplug.
Okay, now we're going to replace the headlight. At this time, you can obviously service the bulbs if that's all you're looking to do. So, they just twist in ... or twist out and twist back in. Then, our headlights come with that whole bracket and everything, so if you're replacing your headlights at this point, you're plugging them in and then everything should install just the same way. Plug them in, put the headlight back in there. Take your pins, put them down through. Obviously you have to make sure that the headlight is all the way back in and lock them into place, and your head light's all set.
Now, we'll do a quick test. Just make sure everything's working. The headlight, the high beam, and the signal are not working. Actually that side marker's not working, so we'll really quickly replace that, and then, you're all set. Hope this helps you out. Headlights are pretty easy to service on these GMC trucks.

All the parts arrived quickly. Was pleased with that. Doing the install is where I found a couple issues. Easy to install, but the drivers side headlight unit is loose fitting. As I went to install the new bulbs I had purchased, both the low beam, and the high beam were way loose. All o-rings were in place. Needed to apply some silicone to the edges, and allow a couple hours before using my headlights.
All the parts look well once installed, but sure a rubber shim will need to be installed to hold the drivers side light in place. Hoped they would have been better. They are made in Taiwan.
I was satisfied with parts I ordered

I will start off by saying that this is my second kit, first kit was for my 2003 Chevrolet 3500. Very impressed again with the fit and finish. I what a great way to dress Your truck up at a very reasonable cost. Service as usual was spot on and I received it exactly when promised. I will be doing business again now that I know what other products they offer for my trucks!!! Thanks again!!!
My GMC is in excellent original condition but the front lights were yellowed and foggy. This 6 piece light kit was exactly what I needed to make it look brand new again!
