Great Replacement
Installed these on my 03 Silverado 2500 HD today and they look great. The originals were so foggy and dull that my wife could always tell it was me coming down our road. I looked at several different sites but this set was by far the best deal. Ordered on a Sunday and got them on a Wednesday. Hoping they hold up and don’t leak, but very satisfied so far.

The Best
The replacement lights I ordered for my 03 Silverado were an exact fit. I would recommend 1A Auto to anyone looking for parts. Great site for how to videos. Courteous and knowledgeable customer service.

Exceeded my expectations
When I ordered the kit, it was due to yellowed headlights and leaking tail lights on a vehicle I bought for commercial use. The lights arrived before the estimated arrival date, and were well packaged. The lights are an exact fit, and look and work great. They even came with all new bulbs and wiring harnesses. This is an incredible value, and has really enhanced the look and value of the truck, not to mention have restored the safety and drivability. Well worth the money! This is my second purchase from 1A Auto, and I will definitely buy again in the future.

Great so far
I installed these last week. Installation was quick - around 30 minutes. I had to do a tiny amount of trimming on the clips for the upper headlights. It was done easily with a pocket knife. Each assembly came with bulbs except for the bumper lights (you can see that in the picture but I wasnt expecting bulbs). My truck looks much better now.

Great deal
Look awesome, way way way better than the factory ones that were getting yellow and scuffed up. These are crystal clear and make my truck look way newer than it is. Seriously if youre thinking of selling your truck, or just want it to look nicer for yourself. Cannot go wrong with these at this price, takes years off. Only reason for four stars is that the taillight housing didnt fit perfectly at first, had to file down some of the plastic on the back so it would slide into place properly. Really not a big deal if you have a file and an extra 20 minutes to fix it.

A New Truck Look
bought my 2003 Silverado just a few weeks ago. The rear and front light were faded chipped and had water in the lens. This ready to go light replacement kit totally exceeded my expectations. Only took me about an hour for a brand new look. I’ll be back to shop at A1Auto soon.

Corey M June 10, 2019
The rear set comes with bulbs and new wiring harness. Front is just the housing.
Arthur B June 10, 2019
Mine came with bulbs and sockets for the headlights, brights and dims, and all the taillight bulbs and sockets, but not the front turn signals or daytime running lights
F L June 11, 2019
Yes ours did, but they tell you to replace them. I think its because those are just for testing and not as good of quality needed to drive
