Recommended Surface Mount Submersible Back Up Light For 3" Crossmember on Boat Trailer

Updated 09/09/2024 | Published 09/08/2024

Question:

I am looking for surface mount submersible two-wire back-up reverse lights for a boat trailer that will mount onto a 3” crossmember. Can you help me find those? I have existing ones currently but they are junk and can tell they will fail soon. Much appreciated. Thank you.

There are no 2 wire taillights that are going to have a backup feature.

You'll want to pick up the # STL68RB which is surface mount submersible and has the reverse light feature, but has 4 wires. You'll be able to mount these to a 3" crossmember as the bolt holes are 2-5/8" apart, though you'll have to drill a hole into it for the wires to pass through.

Thanks but I’m not looking for taillights with a reverse light function. I’m looking for separate LED back-up lights.

@Keith Ok. Based on your same 3" crossmember you'll need to go with # BUL111CFPG which will fit perfectly though you'll still need to drill a hole for the wires to go through the crossmember. You will also need # A45CB to plug into the light.

@SamuelC Thanks. But unless I'm missing something, or reading it incorrectly, this product is 3 5/16" tall according to the description. Is the black bezel removable to allow it to fit on the 3" crossmember?

@Keith The screw holes are 2-11/16", so they will fit into the crossmember. There's nothing that's exactly 3" that will fit perfectly to the crossmember. If that 5/16" makes a difference, offset the light down or up and only use 3 of the screw holes, and trim the black plastic to match the crossmember perfectly.
