Easier than appeared
It was a perfect fit and appears to be of OEM quality. One reason I like to buy from 1A is the repair videos, but this one was easier than the video depicted. The videos still give you an idea of what you are getting into. I did not raise the glass, I raised the hatch only. It took maybe 15 minutes and I was done.

Excellent product!
Following the YouTube video on installation, I purchased the High Mount Third Brake Light product. Installation was exactly as the video depicted. For under $50, installation was completed in less than 5 minutes. Cost estimate to do the same thing at the Chevrolet dealer was $350. At our local repair shop, the estimate was $225. Thank you 1A !
October 19, 2018
Ordered the part 10/24/18. Part showed up on 10/25/18 at 10:45am. Cant ask for any better than that. All you need is a Phillips Screwdriver to remove the 2 screws. Pull the light toward you to get the center pin in the back out. Then twist moving past the rubber weather stripping. Pull off the wire connection. Transfer the Gasket onto the New Light. Install the wire connection onto the new light. Have somebody hit the brake to test it. Then carefully slip the light back into the pocket, tighten the 2 screws, and youre done. Im happy.

Ask a question to 1A Auto customers who purchased the product
What type of bulbs do they take?
Ruben B April 26, 2019
Its a sealed unit. You have to buy the whole unit.
D D April 26, 2019
These will be the same bulbs that were in your original assembly. These are not serviceable, you would have to buy the assembly to get new bulbs.
Ian P April 26, 2019
It’s a sealed unit with LED’s. The bulbs are not replaceable, you have to replace the whole thing.
Scott J April 27, 2019
The light is a sealed unit to make it weatherproof. It doesn’t appear that it can be opened to change bulbs. The unit has to be replaced when there’s a problem.
