Hey Eric! The single wire for the Thinline LED Clearance and Side Marker Light # AL91RB is the # A91LW. If you need the self-grounding mounting bracket it is # A91BB for black or # A91CB for chrome. Don't hesitate to reply below if you need anything else.

Hey Eric, did the single wire plug work out for your Thinline LED light? I'm asking because your experience could help others looking for a similar setup.

@RobinH the single wire did work with the thinline led. The problem I had and others have had after I posted on a horse trailer page is that the female plug on the led sticks out further than the factory light I was replacing and it was grounding/ shorting against the aluminum body . I took liquid electrical tape and covered the connection at led and single wire plug and all is good . But took several days of troubleshooting to find the issue.
