Partsam 12V Submersible LED Trailer Lights, Rectangular Low-Profile IP68 Sealed Combo Kit (Pair)

Partsam 12V rectangular submersible LED trailer lights are a sealed, low-profile taillight kit that delivers seven combined functions — stop, tail, turn, marker, clearance, reflex and a built-in license plate lamp — for boats, trailers and trucks.

These compact, DOT-compliant lights are engineered for marine and road use where water, vibration, and weather are routine challenges. Each light is fully welded and sealed with an IP68 rating so it can be submerged and still protect the circuit board and diodes. The kit includes both left and right lamps, stainless mounting hardware, and reflective stickers, making it a practical upgrade for trailers, RVs, utility vehicles and work trucks.

How do these lights perform in wet or submersion conditions?

The lights are built to resist water intrusion with a welded lens and sealed circuit board, plus a designed drain path to keep moisture away from the diodes. IP68 certification means the assembly is rated for continuous immersion when installed per guidelines.

• Fully welded housing prevents lens screws from loosening and leaking
• Sealed circuit board and isolated center chip to block water contact
• Drain channel directs any trapped water away from LEDs
• IP68-rated for continuous submersion protection

What light functions and LED configuration are included?

These rectangular combination lights deliver seven functions required for wider trailers when mounted correctly: stop, tail, turn, side marker, side reflex, rear clearance, plus a license plate lamp on the driver-side unit. The left lamp contains 22 diodes including four dedicated to the license plate, while the right lamp uses 18 diodes for balanced brightness and function.

• Seven combined functions in one sealed unit
• Left light: 22 LEDs (4 for plate illumination)
• Right light: 18 LEDs for rear signaling
• Designed for trailers wider than 80 inches when installed properly

How easy is installation and what hardware is provided?

Installation is straightforward for most trailer and vehicle owners: each light is low-profile and ships with stainless steel mounting screws, bolts and hardware for both under- and over-80" marine towing setups. Note that the kit does not include a wiring harness or mounting brackets, so you may reuse existing harnesses or purchase a compatible one if needed.

• Light dimensions: 8.42" L x 3.27" H x 2.87" W for low-profile fit
• Includes stainless steel screws, bolts and hardware
• Reflective stickers included for added visibility
• Wire harness and mounting bracket sold separately

Are these lights compliant with regulations and built to last?

Partsam uses quality components and builds these lights to meet DOT standards, offering durability against road vibration and harsh conditions. The welded assembly and robust materials are chosen to minimize maintenance and maximize service life in marine and towing environments.

• DOT-compliant construction for road legality
• Rugged build to withstand vibration and weathering
• Welded seams reduce points of failure and leaks
• Designed for trucks, trailers, boats, RVs and utility vehicles

Who is this for: The Partsam 12V submersible rectangular LED tail light kit suits boat owners, tow professionals, tradespeople and fleet operators who need a compact, weatherproof lighting solution for trailers wider than 80 inches or for vehicles exposed to heavy moisture. If you want a low-profile, sealed taillight that provides multiple lighting functions, DOT compliance, and hardware for direct mounting, this kit is a practical fit.
