• Locating the Model Number for a Replacement Tail Light Lens
  The lens will typically have a DOT number, but not a model number. A replacement lens is usually determined by the model number of the light itself. There should be a model number printed on the back of the light. If you have a square incandescent over 80 inch light like the Optronics Submersible Trailer Light, # ST5RB, that you referenced, then the Replacement Tail Light Lens, # A8RB, on your light. If not, then you can send me the model number of the light you have and I can make...

• Boat Trailer Tail Lights Stopped Working After Backing Trailer in Water
  There is a subtle difference between submersible lights like # ST5RB and completely sealed lights. Submersible lights will let in water but will allow it to drain out. Sealed lights will keep water out and as such are also submersible. Part of the problem is that you really need to disconnect the trailer wiring prior to submerging the trailer in the water since the light is not sealed and the connection splices are not water tight. The brake light/turn signal functions not working could...

• Replacement Lens for Tail Light
  The code numbers and letters on a light lens are NOT usually the light's actual part number. Usually the actual manufacturer part number for the light appears on the base portion that is secured to the trailer and the lens has only DOT codes.

• Trailer Wiring Recommendation for a 1991 Toyota Camry
  Your best option would be to replace the old style of trailer connector you have on your 1991 Toyota Camry with a new wiring kit like part # C56175 that will give you a 4-way on your vehicle to match the 4-way on your trailer. Without knowing more about what kind of wiring you have on the Camry it would be very hard to figure out what you would need to do to make the kit work. I attached a review video for this wiring harness plus an FAQ on trailer wiring for you to check out as well.
