Partswcgg 4" Round LED Trailer Tail Lights 8 Red + 4 White — 12V, IP67 Waterproof, 24-LED

Partswcgg 4" Round LED Trailer Tail Lights are a waterproof, 12V LED lighting kit that includes eight red stop/taillights and four white reverse lights for universal trailer and truck use.

These compact 4-inch round LED units deliver bright, low-current illumination in a sealed housing designed for exterior vehicle applications. Each lamp contains 24 LEDs and connects via a standard three-prong pigtail with a rubber grommet for flush mounting. The set blends stop, turn, tail and reverse functions into a ready-to-install package suitable for most 12V trucks, trailers, UTVs and utility vehicles.

How do these lights install on trailers and trucks?

Installation is straightforward: each light is a flush-mount fixture that uses a rubber grommet and a 3-prong wire pigtail. You’ll need a roughly 4.5-inch mounting hole and basic wiring skills to match the color-coded leads.

• Flush-mount design with rubber grommet for a snug fit
• Standard 3-prong pigtail: white = ground, red = high mode, black = low mode
• Recommended hole diameter: approximately 4.5 inches
• Sonically sealed housing simplifies exterior installation

What lighting functions and electrical specs do they support?

Each red lens provides stop, turn, brake and tail light outputs, while the white lenses serve as reverse/backup lights. The LEDs run on 12V DC and use less current than incandescent bulbs, producing quicker illumination with lower heat output.

• 24 LEDs per light for improved visibility
• Rated for 12V DC systems common to trailers and pickup trucks
• Faster light-up time than incandescent bulbs, improving response
• Lower power draw and reduced heat generation

Are these lights durable and weather resistant?

Yes. The lights are sonically sealed into an IP67-rated housing, making them resistant to dust and able to withstand temporary immersion. That sealing plus the lens quality helps keep moisture and road grime out for reliable outdoor use.

• IP67 waterproof rating for submersion protection
• Sealed lens and housing to prevent water ingress
• Durable LED array resists vibration and shock from road use
• Suitable for exposed mounting on trailers and utility vehicles

What are the physical dimensions and compatibility details?

The outer diameter measures about 5.2 inches while the visible inner lens is roughly 4.1 inches. With the grommet installed, the profile height is near 1 inch depending on insertion depth, and the lights are designed for universal compatibility with most 12V vehicles.

• Outer diameter: 5.2 inches; inner lens: 4.1 inches
• Projected height with grommet: approximately 1 inch
• Works with 12V systems on trucks, trailers, UTVs, pickups and more
• Set contains eight red 4" stop/taillights and four white 4" reverse lights
