Partswcgg 4" Round LED Trailer Tail Lights 12V 24-LED (8 Red + 4 White) IP67 Waterproof, Flush-Mount

These Partswcgg 4-inch round LED trailer tail lights are a 12V, flush-mount lighting kit with eight red stop/turn/tail LEDs and two white reverse LEDs, delivering brighter, faster, and more efficient illumination in an IP67 waterproof housing.

Upgrade trailer visibility with a compact, sealed LED lighting solution built for trucks, trailers, UTVs and other 12V vehicles. Each unit uses 24 high-output LEDs in a durable round housing with rubber grommets and a standard three-prong pigtail for straightforward installation. The sonic seal and waterproof lens keep the electronics protected from road spray, mud and accidental submersion.

How do these lights improve safety and visibility on the road?

The LEDs light faster and brighter than incandescent bulbs, making brake and turn signals more noticeable to following traffic. The kit includes separate red lights for stop/turn/tail functions and white lights dedicated to reversing, which helps other drivers understand your vehicle’s actions clearly and quickly.

• 24 LEDs per lamp for even, high-visibility illumination
• Faster response time than incandescent bulbs
• White reverse lamps for clearer backup visibility
• IP67 rating protects electronics in wet conditions

What does installation look like and what hardware is included?

These are flush-mount lights supplied with rubber grommets and standard three-prong wire pigtails for a clean install. The white wire is ground, red is high mode, and black is low mode — compatible with most 12V trailer wiring systems.

• Flush-mount design with rubber grommet for vibration cushioning
• 3‑prong pigtail pre-wired for quick connection
• Recommended hole size about 4.5" for proper fit
• Sonically sealed lens/housing to keep water and dust out

Are these lights durable enough for heavy-duty and marine use?

The housing and lens are sonically sealed to meet IP67 standards, meaning the unit is water-resistant and can handle temporary submersion. LEDs run cooler and draw less current than incandescent bulbs, which reduces stress on the lamp housing and extends service life in harsh environments.

• IP67-rated waterproof and dustproof construction
• Sonic sealing prevents moisture entry around the lens
• Low current draw reduces heat and power strain
• Robust plastic housing resists impact and vibration

What are the exact dimensions and vehicle compatibility?

The outer diameter measures about 5.2 inches, while the inner bezel is approximately 4.1 inches. Height with the grommet is around 1 inch, and you should plan a roughly 4.5-inch hole for mounting. These lights are universal for most 12V systems found on trailers, trucks, pickups, UTVs and similar vehicles.

• Outer diameter: 5.2 in • Inner diameter: 4.1 in
• High with grommet: about 1 in (varies by installation depth)
• Designed for 12V DC vehicle electrical systems
• Suitable for stop, turn, tail, marker, and reverse functions

Who is this for? If you tow regularly, maintain a fleet, or need reliable exterior lighting for off-road and marine trailers, this Partswcgg kit is tailored for owners who want a compact, sturdy, and easy-to-install LED solution.
