Trailer Side Marker Lights

These Boat Trailer Side Marker Lights are submersible, meaning they will perform perfectly when dunked in the water at the boat ramp. We have LED and Incandescent versions in Red and Amber, depending upon your needs and uses. With so many different options available on the market, it is difficult to carry every option, so we have compiled a list of the most common and reliable versions available.
