Partsam 12V LED Submersible Trailer Lights Pair — Rectangular Low-Profile, IP68 Waterproof, DOT-Compliant

Partsam 12V rectangular low-profile LED trailer lights are a fully sealed, submersible combination kit that provides stop, tail, turn, license, marker and reflex functions for trailers, boats and trucks.

This pair of Partsam lights is built for wet and rough conditions: welded housings, IP68 submersion rating and zinc-plated mounting hardware make them suitable for marine towing and heavy-duty road use. Each lamp is pre-wired and optimized to replace conventional rectangular tail lights on trailers wider than 80 inches when mounted correctly, with one unit including a built-in license plate lamp.

How do these lights handle water and vibration?

Partsam designed the lights specifically to resist water intrusion and survive constant vibration. The lenses are welded to the housing, the circuit board is sealed, and an intentional center chip and drain path channel water away from electronics.

• IP68-rated for continuous submersion and harsh marine exposure
• Welded, screwless lens-to-housing joint prevents leaks
• Internal drain/chip design routes water away from the LED board
• Zinc-plated hardware reduces corrosion in saltwater environments

What lighting functions does each unit provide?

The kit supplies multiple legally useful lighting roles in one compact rectangular housing. When installed as intended, the pair covers stop, brake, turn, running, side marker, rear clearance and rear reflex duties, plus a built-in license plate light on the driver's-side lamp.

• Driver-side lamp: 22 diodes including 4 for the license plate illumination
• Passenger-side lamp: 18 diodes for standard tail functions
• Combination output reduces the need for separate fixtures
• Designed to meet DOT visibility and configuration expectations

How straightforward is installation and what hardware is included?

Each light is a low-profile rectangular unit sized to match common trailer mounts and comes with corrosion-resistant mounting bolts and screws. The package contains reflective stickers too, but note that a wire harness and bracket are not provided, so some vehicles may require an adapter or basic wiring work.

• Single lamp dimensions: 8.42" L × 3.27" H × 2.87" W for compact fit
• Included: 2 lights, zinc-plated mounting screws/bolts and 4 reflective stickers
• Not included: wire harness and mounting brackets—installers should supply as needed
• Hardware suited for both under-80" and over-80" trailers when mounted properly

Are these lights DOT-compliant and suitable for road or marine use?

Yes — Partsam builds these lights to comply with DOT standards while also meeting IP68 waterproofing for marine environments. They are meant to function reliably on trailers, boats, campers, utility vehicles and similar towed equipment without compromising safety or legal visibility.

• DOT-compliant design for on-road legality
• IP68 submersible rating for consistent marine performance
• Durable components chosen for conductivity and long life
• Sealed circuit board to prevent shorting from moisture

Who is this for? These Partsam rectangular LED lights are targeted at owners and operators of boat trailers, utility trailers, RVs, trucks and other towed equipment who need a compact, durable, multi-function tail light solution that resists saltwater and harsh road conditions. They suit do-it-yourself installers and professional shops replacing aging lenses with a sealed, DOT-compliant kit — ideal when a low-profile, waterproof fixture and an integrated license lamp are required for safer towing.
