Nilight 6-inch Oval LED Trailer Tail Lights — 4-Pack Red, Grommet Mount, IP67 Waterproof High-Visibility

Nilight 6" Oval LED Trailer Tail Lights (red) are a 4-pack of grommet-mount, IP67-rated LED lamps serving tail, brake, and turn signals for 12V trailers and trucks.

These oval LED tail lamps combine a slim 6-inch profile with a cluster of SMD diodes to deliver high-visibility red output for stop, turn and taillight functions. Each lamp ships with a molded grommet for surface mounting plus a three-prong watertight plug and attached wiring so you can fasten and wire them quickly without extra brackets. The units are silicon sealed and rated IP67 to withstand rain, mud and car-wash conditions.

How bright are these lights and how do they show turn, brake and tail functions?

Each lamp uses 10 SMD LEDs arranged to produce a bright red signal for braking and turning while offering a lower-intensity mode for running lights. That separation of intensities improves on-road visibility and helps other drivers recognize your intent sooner. The LEDs are designed for consistent output and long life compared with incandescent bulbs.

• 10 high-quality SMD LEDs per housing for strong red output
• Distinct brightness levels: high for brake/turn, low for tail
• Uniform beam pattern to reduce glare and improve recognition
• Energy-efficient LEDs draw minimal current from a 12V system

What makes the grommet mount and plug design easier to install?

Nilight designed the light with molded "ears" and upgraded grommet notches so the lamp seats securely in the rubber sleeve and resists twisting or pulling out. The supplied three-prong watertight plug snaps into place and has attached wires, so installation is typically surface-mounting the grommet, pressing the lamp in, and connecting the three wires to your vehicle harness. The package also lists the required mounting hole size to help you prepare the cutout accurately.

• Surface-mount grommet included for a flush, vibration-resistant fit
• Upgraded notches and side "ears" to lock the lamp into the grommet
• 3-prong watertight plug with attached wires for quick hookups
• Mounting hole guidance: check specified hole dimensions before cutting

Are these lights durable against weather and road conditions?

Yes — the housings are heavily silicon sealed and carry an IP67 waterproof rating, meaning they are protected against dust ingress and can survive temporary immersion. The sealed electronics and sturdy lens resist road grime, salt, and most wash cycles, making them well suited for trailers, work trucks, and farm equipment used in varied conditions. LEDs also tolerate vibration and shock better than filament bulbs.

• IP67-rated: dustproof and protected against temporary immersion
• Silicone sealing around the housing to prevent moisture entry
• Shock- and vibration-tolerant LED assembly for rugged use
• Corrosion-resistant materials appropriate for road salt exposure

Will these work on my vehicle — voltage and compatibility notes?

These lights run on standard 12V DC systems and are intended for use as taillight, turn signal, and brake lights on trailers, trucks, tractors and similar vehicles. They are universal in application but check the mounting hole dimensions and wiring compatibility before purchase to ensure a proper fit and function. If your vehicle uses a different connector or voltage, an adapter or wiring changes may be required.

• Designed for 12V DC electrical systems
• Functions: turn signal, brake light, taillight in one unit
• Universal fit for trailers, trucks, RVs, tractors and more
• Confirm mounting hole dimensions and wire color mapping before install
