Partswcgg 4" Round LED Trailer Tail Lights 8 Red + 4 White - 24 LED, IP67 Waterproof Flush-Mount

Partswcgg 4" Round LED Trailer Tail Lights are a waterproof, flush-mount 12V lighting kit with 24 LEDs per lamp, designed for stop/turn/tail and reverse functions on trailers and light trucks.

These 4-inch round LED lights come as a complete set with grommets and standard 3-prong pigtails for simple installation. Each red lamp houses 24 bright LEDs for clear stop, turn and tail signaling, while the white lamps function as reverse/backup lights. The units are sonically sealed to IP67 standards so they resist dust and temporary submersion, and they run on 12V DC systems common to trailers, pickups, UTVs and small trucks.

How do these lights install on my trailer?

Installation is straightforward: the lights are designed as flush-mount units with rubber grommets and include 3-prong wire pigtails for power connections. You’ll generally need to drill a hole roughly 4.5 inches in diameter to seat each lamp, then connect ground, high and low wires to your trailer wiring harness.

• Flush-mount design with rubber grommets for secure fit
• Standard 3-prong pigtail: white = ground, red = high, black = low
• Outer diameter 5.2", inner diameter 4.1", height ~1" with grommet
• Works with 12V DC systems—no special adapter needed

What performance and durability can I expect?

Each LED lamp contains 24 LEDs that light faster and draw less current than incandescent bulbs, offering improved visibility and lower power consumption. The housing is sonically sealed and rated IP67, providing protection against dust and temporary water immersion.

• 24 LEDs per lamp for brighter, quicker illumination
• IP67 waterproof housing and lens—submersible in short durations
• Lower heat generation and reduced current draw versus incandescent
• Sonically sealed unit resists vibration and environmental exposure

Which functions do the red and white lamps serve?

The red round lights are multi-function: stop, turn, tail, running and marker duties. The white round lights act as reverse/backup lamps to illuminate behind the vehicle. Wiring color codes make it easy to assign each lamp its intended role.

• Red lamps: stop, turn signal, brake, tail and marker lights
• White lamps: backup/reverse illumination
• Wiring: white = ground, red = high output, black = low/output
• Universal fit for trucks, trailers, pickups, UTVs and more

What should I know about sizing and compatibility?

The visible mounting face measures roughly 5.2 inches across, with an inner bezel near 4.1 inches; plan for a 4.5" hole for best fit. These lights are built for standard 12V systems and are compatible with most light-duty vehicles and trailers.

• Outer diameter: 5.2"; inner diameter: 4.1"; mount hole ~4.5"
• High with grommet about 1" depending on fit depth
• Universal 12V compatibility—works on trailers and light trucks
• Sold as a set including grommets and pigtails for full installation
