Partsam 4-inch Round LED Trailer Tail Light Kit — 4-Pack (2 Red + 2 White), 12‑LED, IP65 Recessed

Partsam 4-inch round LED tail light kit delivers stop, turn, tail and backup lighting in a waterproof, recessed-mount set for trucks, trailers and RVs.

This kit contains four 4" LED lamps—two red for stop/turn/tail functions and two white for backup/reverse—plus rubber grommets and 3-prong wire pigtails for a complete recessed installation. Built for 8–16V DC systems, the lights use 12 high-efficiency LEDs that draw little current and light instantly compared with incandescent bulbs. They are sealed for weather resistance (IP65) and designed to fit a roughly 4.5" mounting hole with a 5" grommet ring.

How do these lights install on my trailer or truck?

Installation is straightforward for recessed-mount applications: drill the recommended hole, seat the included rubber grommet, then feed and connect the three-prong pigtail. Color-coded wires make wiring intuitive—white is ground, red is high-brightness, and black is low-brightness—so you can integrate into existing circuits quickly.

• Recessed-mount design with 5" grommet ring and ~4" inner diameter.
• Drill a ~4.5" hole for proper fit and sealing.
• 3-prong pigtails included for plug-and-play wiring.
• Color-coded leads: white (ground), red (high), black (low).

Will the lights hold up outdoors and in rough conditions?

These LEDs are sealed and rated IP65, protecting against rain, splashes and dust; they are not intended for continuous submersion. The housings are impact resistant and the LEDs run cooler and draw less current than incandescent lamps, which reduces thermal stress and improves longevity.

• IP65 weatherproofing—resists water spray and dust intrusion.
• Impact-resistant construction to tolerate vibration and shocks.
• Low power consumption for reduced heat and longer life.
• Water-tight sealing around the lamp lens and housing.

What electrical systems and vehicle types are compatible?

The kit is engineered for 8–16V DC systems and is compatible with most light circuits on trailers, trucks, RVs and many work vehicles. It supports stop, turn and tail signaling on the red lamps and backup/reverse illumination on the white lamps, accepting standard three-prong trailer connectors used across many platforms.

• Works with 8–16V DC power systems (typical 12V vehicles).
• Fits many vehicle types: pickup trucks, trailers, RVs, buses, utility vehicles.
• Accepts standard 3-prong plug wiring for common trailer harnesses.
• Includes two red (stop/turn/tail) and two white (backup) lamps.

How bright and responsive are the LEDs compared to bulbs?

The 12-diode assemblies provide crisp, fast-acting illumination that reaches full brightness instantly, improving signal recognition compared with incandescent bulbs. Because LEDs switch on faster and produce focused light, they improve visibility for following drivers while consuming less power overall.

• 12 high-efficiency LEDs per lamp for bright, even output.
• Instant-on illumination for quicker signaling response.
• Lower current draw than incandescent equivalents.
• Designed to resist shock-related damage and filament failure.

Who is this for: drivers, fleet managers and DIY technicians who need a reliable, cost-effective LED replacement kit for stop/turn/tail and reverse lights on trailers, pickups, RVs and work vehicles. Choose this kit if you want a recessed, weather-resistant installation with included grommets and plug-ready pigtails that fit most 12V systems.
