Partsam 4-inch Round LED Trailer Light Kit — 4 Red + 2 White, Flange Mount Sealed 12V

Partsam 4" Round LED trailer light kit combines four red multi-function lamps and two white reverse lamps in a sealed, flange-mounted package for reliable brake, turn, tail and backup signaling on 12V vehicles.

This kit supplies six 4-inch round LED lamps engineered for trailers, RVs, trucks and other 12V applications. Each red lamp handles stop, tail, turn and parking duties while the white lamps serve as backup/reverse and fog-driving lights. The lights are recessed with an integrated flange for a tidy mounting finish and come hardwired with three pigtail leads for straightforward installation.

How do these lights improve visibility and response time?

LEDs illuminate faster and with greater intensity than traditional incandescent bulbs, helping other drivers notice braking and signaling sooner. The 12 super diodes per lamp deliver a bright, uniform output while consuming less current and producing less heat.

• 12 high-efficiency LEDs per lamp for clear, visible output
• Faster on/off response than filament bulbs
• Lower power draw preserves vehicle electrical resources
• Waterproof sealed design maintains brightness in wet conditions

What mounting and wiring details should I expect?

Each light is recessed with a built-in flange for a clean installation. The lamps are hardwired with three pigtail wires—Black for ground, Red for stop/turn, and White for tail/running—so they integrate with standard trailer wiring systems.

• Recessed flange mount for snug, finished appearance
• Required drill hole: 3.8" internal / 4.2" external diameter
• Three-wire pigtail: black (ground), red (brake/stop), white (tail/run)
• Sealed connections reduce corrosion risk in exposed applications

Are these lights durable enough for trailer and marine use?

The housings and lenses are impact-resistant and each lamp is water-tight sealed to stand up to road vibration and harsh weather. LEDs run cooler than incandescent bulbs and are less likely to fail from shock or heat cycling, extending service life in mobile environments.

• Impact-resistant lens and body to resist road shock
• Watertight sealing for rain, spray and marine exposure
• Lower heat generation reduces stress on internal components
• Hardwired connections designed for steady, long-term use

Will this kit fit my vehicle and what applications is it best for?

These 4" round LED lights are a universal 12V fit suitable for many vehicle types. Their combination of red multi-function lamps and white reverse lamps makes this kit versatile for trailers, motorhomes, service vehicles and boats that need stop/turn/tail plus backup illumination.

• Compatible with 12V electrical systems (trucks, trailers, RVs, boats)
• Useful on pickup trucks, utility trailers, horse trailers and floats
• Works for marine and service vehicles where waterproofing is needed
• Ideal for retrofit replacements or new builds requiring recessed mount lights

Who is this for: The Partsam 4" Round LED light kit is aimed at DIY installers, fleet managers and vehicle owners who want a compact, durable, hardwired lighting solution for 12V trailers and vehicles. It suits those replacing worn incandescent fixtures, upgrading visibility for safety, or fitting new equipment that needs multi-function rear lighting with dependable reverse illumination.
