prolineppi 12V Submersible LED Trailer Lights Pair — Low-Profile Red Rectangular Stop/Turn/Tail, Sealed Polycarbonate

These are a pair of prolineppi low-profile 12V rectangular submersible LED trailer lights, each packing over 12 high-output diodes for stop, turn, tail and license illumination in marine and trailer applications.

Designed for boats, trucks and trailers that need a compact, weatherproof lighting solution, this kit includes two sealed red submersible lights with durable polycarbonate housings and an 8" wiring lead. Each lamp is built to survive temperature swings and wet environments while delivering bright, consistent LED output for signaling and plate illumination. The lights ship from U.S. inventory and are ready to install on most 12V systems.

How bright and reliable are these LEDs for signaling?

Each fixture contains more than 12 super diodes, arranged to provide visible stop, turn and running light output even in daylight. The LED layout emphasizes quick illumination for signaling and sustained output for tail and accessory lighting without filament failure risks.

• Over 12 high-output LEDs per light for strong visibility
• Instant-on LED response improves signaling timing
• Even illumination suitable for license plate use
• Long-lasting diodes reduce bulb replacement frequency

Will these lights withstand immersion and harsh weather?

These lights are submersible and sealed to keep water, dust and salt spray out of the LED compartment. The polycarbonate housing and robust sealing are designed to handle routine immersion and wide temperature swings common in marine and roadside use.

• Fully sealed polycarbonate body resists water intrusion
• Built to tolerate temperature variation without cracking
• Corrosion-resistant materials suited for marine use
• Sealed connectors reduce failure points

How do I wire and install the kit on my trailer or boat?

Each 8" submersible light comes with three wires (one with a grounding ring) to link into standard 12V tail/stop/turn circuits. Installation is straightforward for anyone familiar with trailer wiring: mount the housing, connect the wires to corresponding circuits, and secure the ground ring to the frame.

• Three-wire tail/stop/turn configuration with ground ring
• 8" pigtail simplifies routing through grommets or panels
• Surface-mountable low-profile design fits tight spaces
• Includes two red submersible lights — ready for left/right use

How compact is the low-profile design and where does it fit best?

The rectangular low-profile chassis keeps the lights close to the mounting surface, preventing snagging and improving clearance on trailers and hulls. Their slim profile makes them suitable for license locations, rear bumper mounts, and recessed housing installations.

• Low-profile rectangle minimizes protrusion from surfaces
• Fits on bumpers, sterns, and license mounting points
• Works in both exposed and recessed mounts
• Compact footprint is ideal for tight clearance areas

Who is this for? This prolineppi 2-piece kit is aimed at boat owners, trailer operators and light-vehicle technicians who need a compact, submersible LED replacement for conventional rear signal lamps. If you want sealed, bright signaling with minimal maintenance and a simple three-wire hookup, these lights provide a practical, weather-resistant option ready to ship from U.S. stock.
