Question:
Need a pair of fully submersible boat trailer lights. Incandescent bulbs only. Watertight.

Expert Reply:
Hey Don. For submersible incandescent trailer lights, I recommend the Optronics Combination Trailer Tail Light item # ST16RB for the passenger side and item # ST17RB for the driver's side.
These are seven function lights that display stop, tail, turn, side marker, side reflector, rear clearance, and rear reflector. They measure 8-1/16" long x 2-7/8" tall x 2-13/16" deep and have mounting studs spaced 2" apart on center.
I know you are specifically requested incandescent lights for your boat trailer, but I wanted to throw out that the ONE LED Combination Trailer Tail Light item # STL0016RB for the passenger side and item # STL0017RB for the driver's side are the LED equivalents. Their size and function capability are identical to the incandescent ones I recommended. The prices are almost identical but the LED options will last you years longer than incandescent bulbs.
What kind of boat do you have and what kind of water do you typically use it in? Feel free to answer this and throw in any other questions you have, where it says Add Comment.

Ditto on Kenny's response. I only had to replace one but it wasn't from water damage...backed into a post and busted one.

I have purchased these for my 2021 Tracker Pro Team 195TXW and they work great being under water. I've never had any issues with them, and I highly recommend E-Trailer! They have never let me down!
