How Does Bargman 99 Series Trailer Light # 3499001 Ground to Trailer

Question:

Do the Bargman 99 series lights have provisions for self grounding through one of the mounting screws? I have a Pace trailer that doesnt have a ground wire at the clearance lights, they just ground from the self-tapping screw going into the metal trim.

The trailer clearance/marker light you referenced, Bargman 99 Series # 3499001, grounds through one of the two wire connections made at its rear surface receptacles. The mounting screws for the white base portion do not make any electrical connections. You can attach a ground wire between the light and a rust-free bare metal surface on the trailer, such as one of the mounting holes, to establish your ground connection.

For a light that grounds through its mount you could use # MCL44RB1 from Optronics,
