Partsam 6-Piece 4" Round LED Trailer Tail Light Kit — 4 Red + 2 White, Recessed-Mount Waterproof

Partsam 6-piece 4" round LED tail light kit provides stop, turn, tail, and reverse lighting in a waterproof, recessed-mount design for trailers, trucks, RVs and more.

Upgrade or replace worn trailer lamps with this complete 6-piece assembly that includes four red 4" LED stop/turn/tail lights and two white 4" LED reverse/fog lights, plus rubber grommets and 3-prong wire pigtails for straightforward installation. Built for 12V DC systems and compatible across a wide voltage range, these sealed LED lamps are brighter, draw less power, and respond faster than incandescent bulbs. The kit is designed for recessed mounting and accepts a standard 3-prong connector, making it a practical solution for utility trailers, pickups, horse trailers, RVs and other towed or service vehicles.

How simple is the installation process?

Installation is intended to be fast for anyone comfortable with basic vehicle wiring. Each light includes a rubber grommet for recessed mounting and a 3-prong wire pigtail that plugs into standard trailer circuits.

• Drill a 4.5" hole for the roughly 5" grommet ring and 4" inner diameter lamp.
• Wire color code: white = ground, red = high/bright, black = low/park.
• Push-fit with the supplied rubber grommet for a sealed recess mount.
• 12V DC input; compatible with 8–16V systems for broad vehicle fitment.

What lighting functions do these LEDs provide?

The red lamps handle stop, turn and tail/parking duties while the white lamps serve as reverse or fog/back-up lights. The 12-LED layout delivers clear, quick illumination that improves visibility and reaction time compared with incandescent bulbs.

• Red lights: stop, turn signal, and tail/parking light roles.
• White lights: reverse/back-up and fog-light applications.
• Sealed, water-resistant construction to resist road spray and weather.
• LEDs run cooler and draw less current for lower electrical load.

Which vehicles and setups are these lights compatible with?

This kit is built for universal utility across trailers and vehicles that use standard 3-prong trailer wiring and an 8–16V DC supply. The compact 4" lamp size suits recessed mounts on many trailer styles and small trucks.

• Fits trailers: utility, enclosed, boat, horse, and parade floats.
• Works on vehicles: pickup trucks, service vans, UTVs/UTEs, and buses.
• Accepts standard 3-prong trailer connectors and grommet-recessed mounting.
• IP65-rated for splash and weather resistance (not for underwater use).

How durable and reliable are these LEDs for towing use?

Each lens and housing is sealed against moisture and built to resist impact and vibration common in towing and commercial work. The LEDs use high-quality chips for long life and consistent light output under load.

• Water-tight sealed housings and rubber grommets to reduce ingress.
• Impact-resistant construction less prone to shock damage.
• Lower heat generation improves longevity versus incandescent bulbs.
• Designed for repeated on/off cycles and frequent road use.
