Partsam 12V Submersible Square Led Trailer Lights

These square LED lights combine a rugged polycarbonate lens and ABS housing with a dense LED array to deliver bright, reliable signaling for boats, utility trailers, small trucks and farm equipment. Designed to resist immersion, salt spray and road debris, they replace older incandescent fixtures with lower current draw and longer expected life. The left lamp includes an integrated white LED for license-plate illumination while both units act as tail, stop and side marker lights.

How bright and versatile are these LEDs for trailer signaling?

The lights use dedicated LED diodes arranged for separate functions so each signal is crisp and easy to see. With dedicated circuits for high-brightness stop/turn and lower-brightness running lights, they meet common visibility needs without complex wiring changes.

• Left lamp diode layout: 19 diodes for red functions plus 4 white diodes for license illumination.
• Right lamp diode layout: 15 red diodes plus 4 white diodes for balanced tail output.
• Separate wires provide distinct stop/turn and running outputs for precise control.

Will these lights survive water exposure and rough conditions?

Yes — each light is built with impact-resistant PC lenses and an ABS housing and carries an IP68 waterproof rating, meaning they are designed to resist immersion and protect internal circuits in wet environments. The sealed construction reduces corrosion risk and improves reliability for marine and winter use.

• IP68 rating for protection against continuous immersion in water.
• Impact-resistant polycarbonate lens reduces cracking and clouding.
• ABS housing resists UV and road-salt degradation for long-term use.

How does wiring and installation work for these square trailer lights?

Installation is straightforward with color-coded wires and included gaskets and screws. The wiring separates ground, high-brightness brake/turn and low-brightness running/marker functions so you can connect to standard trailer harnesses or integrate into custom wiring.

• White wire = ground; ensures safe return path for all circuits.
• Yellow/Green wire = high brightness for stop and turn signals.
• Brown wire = low brightness for running, tail, side marker and license light.
• Package includes two lamps, gaskets and mounting screws for quick fitment.

Do these lamps fit my vehicle and what should I expect from maintenance?

They are designed for universal mounting on trailers under 80" and suit a wide variety of vehicles like boat trailers, utility trailers, tractors and small trucks. LEDs require minimal upkeep compared with bulbs, but periodic checks of seals and wiring are recommended to maintain weatherproofing.

• Universal fit for trailers under 80" and many commercial/light-ag equipment applications.
• Low-maintenance LED operation reduces bulb changes and current draw.
• Inspect gaskets and connectors seasonally to preserve the IP68 seal.

Who is this for: These Partsam square submersible LED lights are aimed at trailer owners, boaters, farmers and fleet operators who need compact, durable signaling that withstands immersion and rough conditions. Choose this kit if you want a low-energy, long-life replacement for incandescent tail lights with integrated license illumination and simple, color-coded wiring for fast installation.
