Left Rear Brake Light Not Working

[DeanHensler]

My RR and 3rd brake light work.  I put a brand new bulb in the LR and it still doesn't work.  I checked the plug for ground and power and everything looks right.  Can anyone suggest a next step?  See this video for my diagnostic.  https://drive.google.com/file/d/1CuTCYWrE6UfZS8n1R_p4IkXuDgkLsroZ/view?usp=sharing

That is strange for sure.  I made a comment earlier but after watching the video again I deleted what I wrote.  You have running lights, but no brake light. Weird.  The only thing I can think of is get a new harness and try it.   Surely, someone more knowledgeable than me can help.

Bad bulb? Bad socket? correct bulb? try the bulb on the other side.
