prolineppi 8-inch Low-Profile 2-Pack 12V LED Submersible Trailer Lights — Sealed, 12+ LEDs, Stop/Turn/Tail

These prolineppi low-profile rectangular LED lights are sealed submersible stop/turn/tail lamps with 12+ super diodes per unit, built for trailer, boat, and marine use.

Compact and waterproof, this two-piece kit replaces conventional bulb fixtures with bright, energy-efficient LEDs in a durable polycarbonate housing. Each 8" light contains more than a dozen high-output diodes to improve visibility while remaining low profile for bumpers, trailers, and transom mounts. The sealed design resists salt spray and wet environments, and the included wiring and ground ring make installation straightforward for 12V vehicle electrical systems.

How do these lights perform in wet or marine conditions?

The sealed construction and polycarbonate shell keep moisture and corrosion away from the LEDs and internal connections. They are designed to be submersible, so brief immersion and heavy spray won’t compromise operation when properly mounted and wired.

• IP-style sealed enclosure prevents water ingress
• Polycarbonate housing resists impact and UV exposure
• Corrosion-resistant terminals and potted electronics

What wiring and connections are required for installation?

Each 8" lamp includes three wires plus one with a factory-installed ground ring for secure chassis grounding. The three-wire lead supports separate stop/turn and tail circuits so you can hook them into standard 12V trailer wiring harnesses without extra adapters.

• Three-conductor wiring: stop/turn, tail/marker, and common ground
• Ground ring attached for reliable chassis connection
• Direct-swap for most 12V trailer and marine light positions

How bright are the LEDs and what functions do they cover?

Each light contains more than 12 high-efficiency super diodes that deliver a bright, consistent beam for stop, turn, and tail functions. The LEDs also illuminate license plate areas when mounted accordingly, providing multi-function performance in a single compact unit.

• Stop, turn, and tail lamp outputs in one sealed assembly
• Over a dozen super diodes for improved visibility
• Low current draw for longer battery life and reliability

Will these lights fit my trailer or boat and how low-profile are they?

The rectangular low-profile design sits close to the mounting surface to reduce snagging and exposure on bumpers and fenders. The slim footprint works well on trailers, boat transoms, RVs, and utility vehicles where a discreet, flush-mounted light is preferred.

• Slim housing for tight clearance applications
• Standard 8" nominal size for common replacement scenarios
• Surface- or bracket-mountable depending on vehicle setup

Who this is for: This prolineppi two-piece LED kit is suited to trailer owners, boaters, and fleet operators who need reliable, waterproof lighting with low-profile styling. Installers and DIYers will appreciate the simple wiring and included ground ring, while anyone needing brighter, longer-lasting stop/turn/tail lamps will benefit from the energy-efficient LED array and durable polycarbonate construction.
