LIGBT 4-Inch Red LED Trailer Tail Lights 4-Pack — IP67 Sealed, Dual-Intensity Stop/Turn/Running

LIGBT 4-inch round red LED trailer tail lights are a 4-piece set of IP67-sealed stop/turn/brake and running lights designed to deliver brighter, longer-lasting illumination for trailers and utility vehicles.

These compact LEDs replace standard incandescent round lamps with a low-current, high-output solution built for outdoor use. Each lamp packs multiple upgraded Piranha-style LEDs into a sealed housing that limits moisture intrusion and improves heat handling. The lights run on 12–24V DC systems and use a three-wire hookup for brake/turn and running-light functions, making them straightforward to install on most trailers and commercial vehicles.

How do these lights improve visibility on the road?

The dense LED array gives a stronger, faster-responding light than traditional bulbs, making braking and turning signals easier to notice. The lamp design also provides a wider beam spread so other drivers can see signals from different angles.

• 16 upgraded Piranha LEDs per unit for higher brightness and quicker response
• Dual-intensity output: separate circuits for high (stop/turn) and low (running) modes
• Wider lighting angle for better side and rear visibility
• Draws less current, reducing load on vehicle wiring and batteries

What makes these lights durable and weather-resistant?

Each housing is heavily silicon-sealed and rated to withstand rain, splashes, and road grime without letting moisture reach the LEDs. The construction emphasizes thermal management and a rugged lens to resist cracking or fogging under normal road conditions.

• IP67-rated sealing protects against dust and temporary water immersion (do not use submerged)
• Improved heat dissipation extends LED life and preserves brightness
• Robust housing and lens resist impact and environmental wear
• Designed for repeated outdoor exposure across seasons

How simple is the installation on trailers and trucks?

Wiring follows a three-conductor method: ground, high-intensity (stop/turn), and low-intensity (running). The lights include three mounting holes for secure fastening; basic hand tools and a matching hole pattern are all that's required for most installs.

• Three-wire hookup: black = ground, red = high/stop/turn, blue = low/running
• Outline diameter ~5.3" with a luminous face about 4" — verify hole size before cutting
• Three mounting holes around the rim for secure attachment
• Compatible with 12–24V DC systems used on many trailers and commercial vehicles

Will these lights fit my vehicle or trailer application?

The lamps were built for broad compatibility across trailers, trucks, and other work vehicles that accept round 4–5" tail fixtures and run on 12–24V circuits. Confirm the vehicle’s hole diameter and wiring configuration to ensure a proper match before purchase.

• Works with semi-trailers, utility trailers, pickup trucks, boat trailers, buses, service vans, and more
• Ideal for both commercial fleets and personal trailers needing reliable signaling
• Universal electrical compatibility with standard 12–24V DC vehicle systems
• Measure existing fixture opening to confirm fit (outline diameter ≈ 5.3")

Who is this for? These LIGBT 4-inch red LED tail lights are suited for fleet managers, trailer owners, and DIY vehicle owners who need brighter, longer-lived signaling lights that tolerate weather and reduce electrical load. They are particularly useful when upgrading from incandescent fixtures or replacing worn or water-damaged round tail lamps on trailers, trucks, and utility vehicles. Note: they are designed for exterior use but should not be submerged continuously.
