The third light underneath the tailgate on my quadrasteer doesnt come on with the drl's or when i turn the fogs on im pretty sure the lights are blown took it off unplugged it etc but can figure out how to open it up either it doesnt open or im just an idiot... dont be to harsh...

It will only turn on with your running lights.

It's a led bar, single plug into the license plate light harness. I think a new one was around $50. 2x7mm screws at either end and 2 plastic clips hold it on.

Check for power at the harness and test the light to verify proper operation.

Yes, if you're getting power to the plug, but the light doesn't work you'll have to replace the whole thing.
