Nilight 4-inch Trailer Tail Lights LED Pair — Red Brake + White Reverse, IP67 Sealed, Easy Install

Nilight's 4-inch dual-function LED trailer lights are a sealed, weatherproof pair combining bright red brake/running illumination with a white reverse ring for safer backing and visibility.

These Nilight tail lamps integrate 16 high-output LEDs in a compact 4-inch housing to deliver clear brake, tail, and reverse signals for trailers, trucks, and utility vehicles running on a 12V DC system. The lamps are built with a polycarbonate lens and a full rubber edge seal to resist impact and exclude moisture, offering dependable performance in rain, mud, and road spray. Installation is designed to be straightforward for common cutouts and replacement setups.

How do these lights improve visibility when driving or reversing?

The lights separate functions into a red outer ring for tail and brake signaling and a white inner ring for reverse illumination, giving distinct, easy-to-read cues to other drivers. High-efficiency LEDs produce bright, consistent output while the reflective lens design amplifies light for better nighttime recognition.

• 16 total LEDs per lamp: 10 red for tail/brake, 6 white for reverse
• Polycarbonate lens enhances light reflection and spread
• Clear differentiation between brake and backup signals

Are these lights durable enough for road and weather exposure?

Nilight designed the housing with a continuous rubber edge and fully sealed outlet to block moisture and dirt, giving each lamp an IP67-level resistance to water ingress. The rugged lens and sealed construction reduce the risk of fogging and electrical issues after exposure to harsh conditions.

• 360° rubber edge for impact protection and secure mounting
• Completely sealed outlet to prevent moisture entry and corrosion
• IP67 waterproof rating for wet-weather reliability

How simple is installation and wiring for these trailer lamps?

Installation is intended for common pre-cut or existing mounting holes: fit the rubber grommet into the hole, press the lamp in place, and connect the color-coded wires. The wiring uses standard trailer color conventions so most owners can complete the hookup with basic tools and a 12V source.

• Mount grommet into pre-cut or existing hole, then push lamp into place
• Color-coded wires: black = ground, red = brake, white = reverse, brown = running
• Works on 12V DC systems—compatible with trailers, trucks, and more

What vehicles and setups are these lights compatible with?

These 4-inch LED lamps are designed for a wide range of towing and work vehicles, including utility trailers, travel trailers, horse trailers, dump trucks, and tractors when paired with a 12V electrical system. Their compact size makes them suitable for retrofit replacements and new builds where a small but bright signal lamp is required.

• Fits trucks, trailers, semi-trailers, horse and travel trailers
• Suitable for tractors and dump trucks with 12V systems
• Common retrofit size for many 4-inch taillight cutouts

Who is this for? If you tow frequently, maintain farm or utility equipment, or need a reliable replacement for worn or fogged factory lamps, these Nilight 4-inch LED tail lights offer a balanced mix of brightness, weather resistance, and simple wiring for DIY or professional installation. They suit users who want clear brake and reverse signaling in a compact, sealed package that holds up to outdoor conditions without complicated wiring or bulky housings.
