Had to unsnap the bulb plastic housing from the lens housing to get tnto fit into the cab opening. I was able to get it into the opening and after about 10min I managed to snap the bulb housing back on while inside the cab opening. PITA
Perfect fit!

No gaps at all. Fits the contour of the truck can perfectly!
Replaced glazed 3rd light

Put this on my 2002 Chevy HD to improve the safety, utility, and look of the 3rd brake light that was heavily glazed over. Close fit but had it installed within 5 minutes. Very pleased, I recommend this.
Not a direct replacement

This light is hard to install, the light sockets on the back of the light are sticking out and must be un-screwed to get the light in the hole. Once you get the light in I could not get my fingers in the space to plug the lights into the assembly. 1A auto has authorized the return of the light. I did locate a direct replacement light at 1A auto, I will need to transfer my light sockets from the old light. This is the first time I have had a problem with any parts I purchased from 1A auto, and I plan to shop with them in the future.
