High Brake Light
This piece fit exactly as advertised as an OE replacement. The video that showed how to replace the light was spot on. It actually was easier to install than to remove to old light. cj - Evans, GA

Great Price, Perfect Fit, and Got Quickly!!
I was actually pulled over not knowing my previous 3rd brake light had burned out. Needing an inspection in the next couple of weeks, it was imperative that I replace the old one ASAP. Advance Auto priced one for me and it was over $100 more that what I spent with 1A Auto! I knew I wasnt going to spend that much for a 3rd brake assembly but for grins checked w/Auto Zone and OReily Auto Parts. They too were way over priced. Obviously, the next thing I did was to go online and search other sources. I immediately found 1A Auto and the price was so low I could hardly believe it. To top it off, they had the exact youtube video I needed to reference how to remove the old one and replace it w/the one I just purchased. Lastly, same day FREEEEE shipping and got it in 2 days.

Just what I needed!!
I talked to a 1A rep on the phone as I had a fitment question. He assured me that the part was just what I needed. He was absolutely right. I was in the process of replacing the wing and the brakelight and needed assurance that this was the right part. Professional service is just what I needed. Quality part and prompt delivery. Thank You.

Easy to install, just like the video says
I received this third brake light and watched the video once prior to installing. It was easy and it took me about 15 minutes total to remove the existing one and to install the new one. Awesome place to buy replacement parts.

Fits well, works great, great price
I was not sure how something like this would work. It arrived quickly, fitted the car perfectly, and works great. The youtube video for installation was awesome. I watched it a couple of times, and was able to get the installation done easily. Would definately recommend this part, and A1 Auto store in general.

Fantastic
This product is super bright and it’s really high quality feeling. It fits my 2002 Bravada which has a different molding than 2003-04 which is awesome because I didn’t have to change another piece out then. It works flawlessly and is brighter than the stock neon one.

What I needed.
The high level brake light replacement part fits and works exactly like the original. Car dealer wanted to replace the light and molding surrounding light for 10 times what I paid for just the light which is all that was needed. Video from 1A Auto showed me exactly how to replace the part.

Perfect Fit
This light was a reasonable price, it was shipped fast and it fit perfectly. I dont think a person could ask for anything more than that and yet I received more. I wasnt sure how to get to the screws so I watched onre of 1As videos on how to do the R & R. So, in my book, it just dont get any better than this.
