I ordered headlights
They fit perfect and looks great
January 21, 2017
Bought these for my 2000 gmc 2500 and could not be happier they made my Truck look like new again.I had no idea how bad my old lights looked until I put these new lights in WOW. Yes I would absolutely tell everybody to buy these lights.

Quick Installation and Look GREAT!
My old lights (factory installed) were starting to yellow on my 2006 GMC Sierra. The rest of my truck looks great, but the yellowed lights aged it. Ordered these, received them within a couple days. Installation was about 15 minutes and my truck looks 10 years newer! Also ordered a pair for my GMC Envoy and those looks great as well. Would highly recommend. The installation is quick and easy and the fit is perfect. The lights are very bright and look great.

Sort of OK
This kit of 4 lights arrived promptly and looked good out of the box. Installation was easy and they even had the headlight bulbs included. After a couple days noticed the parking lights were fogging up after heavy rain, would clear up after a day but kept fogging. Checked them over and seems like a bead of clear silicone is needed on the top seams. These are bright, fitment is good and they look nice on the truck but they seem to be of thinner materials and are lacking proper sealment and venting. Good for a truck you are going to sell.

Great Look
My old lights were yellowed, scratchy and nasty looking. These sure make my old pickup look good again. Great price, perfect fit.

Look like new OEM.
Very satisfied with this new complete light kit. The lights are nice and bright. Transformed my truck, looks new on the front. You will have to adjust them to aim correctly. They were all out of whack. I highly recommend these for the price mostly.

Great value & product
Between a great product & a video that shows you how to remove & install all two front head light & turning lights . Simple step by step awesome. All lights fit as well as if they were from the factory, when it was built! If I ever need any future parts I will check with A1Auto first ! Thanks you again great product

headlight replacement
Fast shipping and a great deal on this 4 pc headlight / parking light replacement. I got 360000 miles out of the original ones so hopefully I can get that on these. The headlight bulbs came with it but no bulbs for the parking lights as noted on the product description. Im happy

Great headlight kits
The headlight kits fit well and appear to be of good quality, however only time will tell. Will be hard to compare to OEM components but if they last 1/2 as long will be a good deal

Will this fit my car? Add a vehicle to make sure
Customer Q&A
Ask a question to 1A Auto customers who purchased the product
After installing the headlights in the headlight kit, do I have to get the headlight aim checked?
Dennis S March 13, 2016
Everything lined up perfectly so I didnt have to adjust anything but Im not sure about any others it might have been the luck of the draw. Install and see if its to your liking
Daniel T March 13, 2016
I did not, it worked fine.
Robert H March 13, 2016
Kenneth B March 13, 2016
Probably so, I had to adjust mine a little.
Greg S March 13, 2016
I did with my vehicle
Gregory V March 13, 2016
Chances are that you will need to have it aligned properly
Jennifer E March 13, 2016
Yes I did .They were of just a little
Kevin S March 13, 2016
Yes, get the aim checked. After installing mine, the aim was off slightly. I was high beam flashed a couple of times before setting the aim correctly.
John P March 14, 2016
May need some tweaking to get perfect but should be pretty close out of the box
Brian F March 14, 2016
yes, i would recommend you do for optima lighting at night
David M March 14, 2016
As a rule, you should always check alignment after install...There will always be slight variances in the parts...
Chris Beanes C March 14, 2016
How do you adjust the lights?
L S August 6, 2017
If you have a gmc or chev you would use the std adjustment that are on the truck or car
Chaz C August 7, 2017
I didnt have to do much adjustment just a turn or so on the adjusting screws on the back of the light
Paul W August 7, 2017
