LIGBT 4" Red LED Round Trailer Tail Light — 16-LED IP67 Waterproof Stop/Turn/Tail, 12-24V

LIGBT 4-inch red LED round trailer tail light is a compact, weatherproof 3-wire stop/turn/tail lamp with 16 high-intensity LEDs for trailers, trucks, RVs, and boats.

These low-profile round lights combine two brightness modes and a sturdy, sealed housing so you get bright signaling without bulky fixtures. Designed to run on 12–24V DC systems, each lamp uses upgraded Piranha LEDs for wider illumination and longer life. The fixture installs with three mounting holes and a simple three-wire hookup: ground, high-brightness (stop/turn), and low-brightness (tail/running).

How bright and durable are these 4" LED trailer lights?

The light uses 16 upgraded Piranha LEDs that deliver strong illumination and broader beam angles than older LED arrays. The LEDs are chosen for improved heat dissipation, which supports steady output and longer service life under frequent use.

• 16 Piranha-style LEDs for higher intensity and wider spread
• Dual brightness: low for running lights, high for stop/turn/brake
• Improved heat dissipation to reduce wear and extend lifespan
• Compact luminous area: 4-inch active light diameter

Will they hold up in rain, mud, or marine conditions?

Yes — each housing is heavily silicon-sealed and rated IP67, protecting electronics against dust and immersion up to one meter. That makes them appropriate for road, off-road, and many marine trailer situations where exposure to spray and puddles is common.

• IP67 waterproof rating for splash and temporary immersion resistance
• Silicone sealing around the lens and chassis reduces corrosion risk
• Robust construction suited to trucks, trailers, and boats

How simple is installation and wiring for a typical trailer?

Installation is straightforward: three wires correspond to ground, high-brightness (stop/turn), and low-brightness (tail). The lens includes three mounting holes so you can fasten the fixture directly to the vehicle’s body or light bracket with common fasteners.

• Three-wire hookup: black = ground, red = high/stop/turn, blue = low/running
• Three-mount-hole pattern for secure attachment with common screws or bolts
• Compatible with 12–24V DC systems found on most trailers and trucks

Are these lights compatible with my vehicle or trailer?

They’re manufactured to fit almost any vehicle wired for 12–24V DC lighting, including trailers, tractors, RVs, and specialty equipment. Confirm the required hole diameter and mounting pattern before ordering to ensure a proper fit.

• Works with 12–24V DC electrical systems
• Suitable for trailers, trucks, RVs, dump trucks, horse trailers, and more
• Measure mounting hole size first to verify compatibility
