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.

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 wasn't going to spend that much for a 3rd brake assembly but for grins checked w/Auto Zone and O'Reily 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.
