Im interested in purchasing a lightbar for my aluminum wider than 80 Boat trailer. Reviewing your installation instructions, I need the MCL97RG for a ground wire. But I dont see you have that lightbar.

Hey Richard. I have the Optronics item # MCL97RPG, which is the Identification Light Bar. This is a 3-light LED assembly designed for trailers over 80" wide. It has submersible lights, a stainless steel base, and grounds through the mounting hardware.

I looked at our inventory and checked online, I could not find a MCL97RG in Optronics MCL97 line.

i attached a diagram below so you could see the dimensions of the Optronics item # MCL97RPG.

What kind of boat do you have?

Hey Richard, how did the Optronics light bar end up working on your boat trailer? I'm curious if the grounding through the mounting hardware gave you a solid connection. Your update could make it easier for others wiring similar setups.
