2006 Hummer H2 left rear bumper turn signal / brake light does not work. Bulb is good, same light works as tail light, but doesn not work as brake light or turn signal. Problem is also present in trailer lighting connector for brake and turn functions.

If the tail light goes out when the brake light goes on, you have a bad ground.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

this is too good

Once you open the tail gate, you will see 2 torx screws going into the side towards the tail light assembly. Remove those 2 screws and the assembly will come right out. Let me know if you need anything else.

from the rear of the bumper

the brake lights and the rear turn signals should be the same bulb check the bulbs to make sure they are not blown does your third brake light work if all brake light are out and the bulbs are good check the brake light switch on the brake pedal

Hello, If the socket is not broken and the metal contacts are not melted, you should be able to reuse the socket. It just got scorched from the bulb reaching 1000 degrees in a fraction of a second. The Tungsten coil inside takes a lot of heat to burn it up. If you can scrape the char off of the contacts and install a new bulb, every thing should work perfectly. I see these sockets charred like this all of the time, even with a good bulb. If the socket is deformed, you can usually go to any parts store and ask them if they can find you one of these sockets. Most of the parts stores have books loaded with aftermarket companies that deal with just this type of scenario. I hope this info helps...

Bad earth connection.Clean or replce wire.

it can be easily changed by removing the plastic cover then u will see the light bulb, don't try to change it from the back, it wont open :)
