Tail Lightbulb Replacement

[gmcspad13]

I just bought a used QS10.0 and am having trouble with my trailer lights. All the lights blink when I turn on the right blinker, and do not respond at all to the left. After some reading, it looks like grounding may be the issue. The ground behind the converter looks fine, so next I want to check the lights, themselves. I'm not familiar with this type of light, though. How do you take out the light assembly to check the wiring? Do I just pull it free of the aluminum bumper? This is a 2005 QS 10.0. Thanks in advance!

It should allow you to pop off the lens cover which would then allow you to access the screws holding it in. Dont quote me on that since I'm just going by memory but I'm fairly sure thats all you need. A flat head screwdriver and a little prying should do the trick.

If you want to post a picture of your lights, or if you can see a model number I might be able to confirm it for you.
