Partsam 4-Inch Round LED Trailer Light Kit — 6-Piece (4 Red + 2 White), 12-LED, IP65, 3-Prong Pigtails

Partsam 6-piece 4-inch round LED trailer light kit provides four red stop/turn/tail lights and two white reverse/fog lights with grommets and 3-prong pigtails for straightforward, durable installation.

This complete lighting set is built for trailers, trucks, RVs and utility vehicles that need compact, bright LED lamps with weather protection and universal wiring. Each lamp uses 12 high-efficiency LEDs, fits a recessed 4" opening with a supplied rubber grommet, and connects via a standard 3-prong pigtail. With IP65 splash resistance and low current draw, the kit modernizes older incandescent systems without major rewiring.

How does this kit simplify trailer light installation?

The kit includes everything required for a recessed mount swap: lights, rubber grommets sized for a roughly 4.5" hole, and 3-prong wire pigtails. Color-coded wiring and a standard 3-prong layout reduce guesswork and speed up fitment.

• Includes 4 red stop/turn/tail lights and 2 white reverse/fog lights.
• Each light ships with a rubber grommet sized to accept a 4" inner diameter lamp.
• 3-prong pigtails match common trailer wiring harnesses for plug-and-play.
• Simple wire colors: white ground, red high-brightness, black low-brightness.

What are the performance features and durability benefits?

Each lamp contains 12 LEDs that run cooler and draw less current than incandescent bulbs, providing brighter and faster illumination. The housings are water-tight sealed and impact-resistant for rugged road use, while IP65 protection keeps out dust and splashes (not for full submersion).

• 12 LEDs per lamp for bright, quick-response lighting.
• Impact-resistant body reduces shock-related failures.
• IP65-rated protection against dust and water spray.
• Sealed construction prevents moisture intrusion into the lamp assembly.

Will these lights fit my vehicle or trailer?

The lights are designed for wide compatibility with 8–16V DC electrical systems, so they work with most trucks, trailers, RVs, boats with trailers, and utility vehicles. The recessed design and included grommets accommodate common 4" cutouts; plan to drill about a 4.5" diameter hole for installation.

• Compatible with 8–16V DC systems used on many road vehicles and trailers.
• Fits semi trucks, utility trailers, pickup trucks, RVs, horse trailers, and more.
• Recessed mount requires approximately a 4.5" mounting hole.
• Works with standard 3-prong trailer connectors for easy wiring integration.

How do I wire and maintain these LED trailer lights?

Wiring is straightforward: white is ground, red is high-brightness (stop/turn/tail), and black controls low-brightness functions where applicable. Routine checks for tight grommet seals and corrosion-free connectors extend service life; LEDs require minimal maintenance compared with bulbs.

• Follow color codes: white = ground, red = high-brightness, black = low-brightness.
• Ensure grommets are seated firmly to maintain the water-tight seal.
• Inspect connectors periodically and clean any corrosion with contact cleaner.
• LEDs have long life; replace entire lamp if housing is damaged or seals fail.

Who this is for: This Partsam kit is suited to owners of trailers, trucks, RVs and utility vehicles who want a cost-effective LED upgrade that fits common recessed mount openings. It’s ideal for fleet operators, DIY mechanics and anyone replacing worn incandescent lamps with brighter, more efficient LEDs while keeping installation simple and compatible with existing 3-prong wiring systems.
