Partsam 4" Round LED Trailer Light Kit — 4pc (2 Red + 2 White), 12-LED, Recessed IP65

Partsam 4-inch round LED kit supplies four waterproof trailer lights — two red stop/turn/tail lamps and two white backup/fog lamps — with grommets and 3-prong pigtails for straightforward recessed mounting.

Whether you’re replacing worn lenses on a pickup, upgrading an enclosed trailer, or adding reliable rear illumination to an RV, this Partsam set bundles everything needed for a recessed, sealed installation. Each lamp houses 12 long-lasting LEDs that light faster and draw less current than incandescent bulbs. The kit fits standard 3-prong wiring and includes rubber grommets sized for a roughly 4.5-inch mounting hole.

How durable and weather-resistant are these LEDs?

These lights are built to withstand road vibration and typical outdoor exposure. The housings are sealed to keep moisture and dust out, and the LEDs are impact-resistant compared with traditional bulbs.

• IP65 rated for water and dust resistance (not for continuous submersion)
• Sealed enclosures reduce fogging and corrosion risk
• Impact-resistant lens and housing to handle road shocks
• LEDs run cooler and last longer than incandescent equivalents

What functions do the red and white lamps perform?

The kit includes two red lamps that serve as stop, turn and tail lights, and two white lamps designed for reverse or fog light duties. Wiring supports both high/low brightness control so each lamp can perform multiple functions depending on your vehicle’s wiring setup.

• Red lamps: stop, turn signal, and tail light functions
• White lamps: backup/reverse or fog illumination
• Three-wire pigtails (white = ground, red = high brightness, black = low brightness)
• 12-volt input compatible with 8–16V DC systems

How easy is installation and what tools or holes are required?

Installation is straightforward for anyone comfortable with basic wiring and recessed-light mounting. The kit includes rubber grommets and three-prong wire pigtails so you can make a clean, weatherproof connection without cutting into housings.

• Recessed mount with included rubber grommets (approx. 5" ring, 4" inner diameter)
• Recommended mounting hole ~4.5"; 1 3/16" thickness accommodates panel depth
• Standard 3-prong plug compatibility for quick electrical hookup
• Plug-and-play pigtails labeled for ground, high, and low brightness

Will these lights fit my vehicle or trailer?

The Partsam 4-inch round lights are designed as a universal solution compatible with most 12V systems. They work across a wide variety of commercial and recreational vehicles so long as the mounting cutout and voltage are compatible.

• Compatible with trucks, trailers, RVs, buses, utility vans, and more
• Works with 8–16V DC electrical systems, nominally 12V
• Recessed mount needs ~4.5" hole and suitable panel thickness
• Includes standard 3-prong wiring for broad vehicle support

Who is this for? This Partsam light kit is ideal for vehicle owners and fleet managers who need a cost-effective, durable replacement or upgrade for rear lighting. It’s particularly useful for trailers, pickups, RVs, and work vehicles that require sealed recessed lights with multi-function capability. Choose this kit if you want brighter, faster-acting LEDs that are easier on your electrical system and include everything required for a tidy, weatherproof install.
