Toad lights - wire length - Problem solved

Here's the Amazon Link for that M42206R Red LED Stop/Tail/Turn Light photo'd above. It's a small surface mount light with three short pigtail wires coming out from under. Furnished with a foam rubber gasket and two stainless steel screws. That's important, because many "truck" versions of this type of light are meant to mount in a cutout in the vehicle, using a grommet-type gasket. They also have a socket for a plug (not included) that keeps the light from mounting flat. They come in Oval and Round.
Or... Boat Trailer Option They mount with 1/4" bolts with nuts. This set is interesting because you can use different bolts and go back or side.
