Partsam 12V Square LED Trailer Light 12V

This square 12V submersible LED trailer light combines visibility and weather resistance for trailers, boats, RVs and other utility vehicles. It brings stop, turn, tail and side marker functions together in a compact sealed lamp, helping maintain clear signaling on wet roads or while launching a boat.

Key Points

The lamp is fully sealed with an acrylic lens designed to keep water out and protect internal circuits. According to the manufacturer, the light is IP68 rated for submersion and is DOT compliant for road use. Two versions cover different functions: a curb/ passenger side unit with 15 diodes and a street/ driver side unit with 19 diodes that includes a white license plate illuminator. Installation is straightforward for standard trailer wiring, and basic hardware such as gaskets and mounting screws are included.

Wiring follows typical trailer light color codes, and while a wire harness is not included, the manufacturer provides wiring details to help with compatibility. Consider that these lights are compact and may not fit all custom brackets without minor adjustments.

Positive Aspects

The LEDs provide high visibility in rain or fog, improving safety during night driving and boat launching. The sealed construction reduces maintenance compared to older incandescent lamps because moisture and corrosion are less likely to affect performance. Also the included gaskets and screws simplify a basic replacement installation.
