This did not fit my 2003 H2 Hummer even though it’s the same part GM has listed, but it’s wrong. My rear sockets are on a harness and not individual. I’m giving good reviews because I received it fast and it’s what GM says it should be. As you can see by the pictures, not even close.

This worked great in the lower tail light on my 2007 Hummer H2. The original one was caked with years of dirt and sand. This really helped fix that for me as I couldn’t even get the old bulb out.
David –
Excellent product! These are also compatible on the lower turn signal lamps on a rear 2005 Hummer H2. We all know that area is prone to mud and dirt getting up in there. Someone posted a video online and I give all the credit to him for fixing this issue. If you take it to a dealer the lower turn single lamp assembly on the rear of the hummer they want over $400.It takes about 10 minutes to replace both sides and you’ll be very happy. While you’re doing it just pop in some new bulbs.

I used this part on a 2008 Hummer H2 for the driver’s side brake light located in the bumper. This part was identical to the part I removed from the truck minus the corrosion. Works great.

Based on the recommendation on what connector fit the 2006 Hummer H2 rear small brake light, it was purchased and installed. Brake light is now operable.
