They arrived fairly quick and were easy to install. It fit like a puzzle. Now Im more visible on the road. Also a plus, it took a couple of years off the car. Would highly recommend 1aauto. Thanks guys!

perfect fit.
The headlights were an exact replacement and it only took a few minutes each side to replace. I would definitely recommend these from 1A Auto. Shipping was fast and packaging was excellent so nothing was damaged during shipping. One extra bonus, it says in the description that the bulbs were not included, but they were and that made it even less work for the installation.

Very very please with my purchase of the headlights when they say they fit 100% guaranteed they mean it they look very good and easy to install and the videos are very helpful and detailed. Thanks for being a great Parts Source

I received the headlight assemblies from 1A Auto and installed them - very easy. Then I took the car to my mechanic to align the headlights. The scanner indicated that the lights were too dim. I contacted 1A customer service and was told that the bulbs are usually not included, and the ones that I got must have been test bulbs from the supplier. Since I threw out the old bulbs (dumb move), now I have to buy new ones. Hopefull this will all work out OK

2003 Impala headlights
After watching 1A Auto video I bought headlights and just snapped them in. Best thing I have done in the past 10 years.

Fit Great
These headlights fit my 2004 Impala perfectly and look good. Watched the video on how to install, and it was easy. After the install I had to play with them some at night on the adjustments, but think Ive got them pretty much dialed in. I would recommend throwing away the cheap bulbs that come in them, my Sylvania bulbs in the old headlights had a better width of illumination.

Replacement Headlights
Replaced my old headlights as they were all scratched and cloudy. Had bought some cheap ones from somewhere else but they didnt last long. Decided to try 1AAuto and was very impressed. Great price, great product. Works as good if not better than the factory OEM parts and for half the cost too. Dont settle for super cheap versions, get some good quality ones like these. Well worth the price. Will definitely buy again in the future.

Ask a question to 1A Auto customers who purchased the product
Replace the driver side low beam light worked for 2 days and now wont work i checked the bulb it relit then the next day went out again now wont come back on i need help???

I am not for sure if the replacement you bought come with lights installed in it or not. I bout both sides that come with lights installed but you CANT use them if they come with it. Those are just test lights. So I would just take the old bulbs from your old set and use them. Thats what I did and it worked oerfect. It is possible you have a faulty bulb even if its new. Hope this helps.
Mike G June 2, 2016
The one thing that I can think of first off would be to make sure the connection to the bulb is good. I would also check to make sure the bulb is still good. My next step would be to take a meter and make sure you are getting power to the light.
