Nilight 4" LED Trailer Tail Lights Pack of 2 — Red Brake with White Reverse Ring, IP67 Sealed, 16-LED Durable Mount

Nilight 4-inch LED trailer tail lights combine red brake/tail illumination with a white reverse ring in a sealed, weatherproof housing for reliable trailer signaling.

These compact 4-inch lamps deliver multiple lighting functions—running/tail, brake, and reverse—using 16 high-output LEDs per unit in a durable, sealed assembly. Built for trailers, trucks, tractors, and other 12V vehicles, the lights are designed to improve visibility at night and in adverse weather while simplifying installation with a rubber grommet mount and four-wire hookup.

How do these lights improve nighttime visibility?

The combination of a red outer LED ring for tail/brake and a white inner LED circle for reverse provides clear, distinct signaling that’s easy to recognize from a distance. The polycarbonate lens and reflective internal geometry boost light throw and make the beam appear brighter without increasing power draw.

• 16 high-efficiency LEDs per lamp for bright, even illumination
• Polycarbonate lens reflects and focuses light for better visibility
• Separate color rings reduce confusion between braking and reversing

Will these lights withstand rain, mud, and road spray?

Yes — each lamp is fully sealed and wrapped in a 360° rubber edge that protects the housing and prevents moisture ingress. The assembly carries an IP67 rating, meaning it resists dust and can survive temporary submersion, so it stays functional through wet conditions and road grime.

• 360° rubber edge for impact and seal protection
• Completely sealed outlet to eliminate moisture entry points
• IP67 rated for dust resistance and temporary water immersion

How simple is the wiring and installation?

Installation is straightforward: press the grommet into a pre-cut hole, seat the light, and connect four color-coded wires. No special tools or complex brackets are required, and the clear wire color code speeds up hookup to standard 12V trailer circuits.

• Mount with rubber grommet into pre-cut or existing holes
• Four wires: black = ground, red = brake, white = reverse, brown = running
• Fits 12V DC systems on trailers, trucks, and agricultural equipment

Are these lights compatible with my vehicle and lighting needs?

These lamps are designed for broad compatibility across trailers, semi-trailers, horse trailers, travel trailers, dump trucks, tractors, and similar 12V platforms. They function as brake, tail/running, and reverse lights and work well as direct replacements or upgrades for worn incandescent fixtures.

• Works on 12V DC electrical systems common to trailers and trucks
• Functions: brake light, running/tail light, reverse/backup light
• Suitable for utility, horse, travel, dump, and semi-trailers

If you tow trailers, operate light-duty commercial vehicles, or maintain farm equipment and want a compact, durable light that clarifies braking and reversing signals, these Nilight 4-inch LED tail lights are a practical upgrade. They suit owners who need a weatherproof, low-maintenance lighting solution with simple grommet mounting and clear, separate signaling for safer night driving and loading. Choose this set if you want improved LED brightness and sealed construction without modifying your vehicle's wiring harness beyond basic 4-wire connections.
