The lights on my boat trailer isn't working. I have brake lights and turn signals but don't have any tail lights. I'm not good with this type of stuff but could be if I could get some input. I'm good with tools but not good with electrical diagnosis. The lights are the sealed rectangular lights with round corners... about 5 inches long lights. Sealed on front and back of light. I've crawled up under the trailer and can't even figure out how to take the light apart as there are no phillips screws etc. Do the seals pop off? If so, do both come off or just one? And does anyone know if it may be a bad bulb causing this or something to do with the wiring?
