Question:
Im looking for a WesBar Fulton 403025 submersible tail light for a boat trailer. Do you have this or a cross and are these left or right side specific?

Hi Alan!
I do have an option for you, but Wesbar's parent company (First Brands) is having some... "issues" as of late and their parts are extremely scarce at the moment. Look them up online and you will see what I mean. Due to this, we have removed all their parts from our site, unfortunately. With that said, check out the following Optronics lights:
Optronics Incandescent Tail Light for Trailers over 80" Wide - Submersible - 8 Function - Driver Side # ST57RS
Optronics Incandescent Tail Light for Trailers over 80" Wide - Submersible - 7 Function - Passenger Side # ST56RS
From the info I have on the Wesbar 403025, the driver side # ST57RS is nearly identical to it. I also included the passenger side light, just in case. The only real difference between these and the Wesbar lights is the way they are connected. The Wesbar used a 2-flat plug and the Optronics lights are hardwired.
What kind of boat are you carrying on your trailer?
