Help Tail Light Problem

[CBoston]

Hey.
So my right rear tail light issue...
The drive light works but the indicator light and the brake light does not work. Bought new bulb changed, and checked fuse all okay...
Whats my next trouble shooting steps ?

check your ground.

Took light out checked grounds, no issues reassembled and now it works haha... Im assuming it must ground off the mount to the tub and me just taking it off and playing around fixed that...
