Partswcgg 4 in Round LED Trailer Tail Lights Kit — 4pc (2 Red Stop/Turn + 2 White Reverse), 24-LED IP65

Partswcgg 4-piece 4-inch round LED light kit includes two red stop/turn/tail lights and two white reverse lights, complete with rubber grommets and 3‑prong pigtails for straightforward 12V trailer and truck installation.

These compact LED assemblies deliver bright, low-current illumination for trailers, RVs and work trucks. Each lamp uses 24 LEDs, fits a 4-inch mounting hole with a 5.3-inch grommet ring, and is rated IP65 for water resistance (not for submersion). The kit is wired for common 3-prong connectors and supports 8–16 V DC vehicle systems, making it a practical upgrade from incandescent bulbs.

How do these lights improve visibility on the road?

The LEDs produce sharper, more consistent light than traditional bulbs, increasing the chance other drivers notice your signals and reverse lights. Lower current draw reduces strain on the vehicle electrical system while maintaining bright output.

• 24 LED chips per lamp for high brightness and even light spread
• Distinct red stop/turn/tail and white reverse functions to avoid confusion
• Low amperage extends battery and wiring life
• IP65 rated housing resists rain and road spray

What does installation require and how do the connectors work?

Installation is designed to be simple: drill a roughly 4.6" hole for the grommet, push the lamp into the rubber ring, and connect the 3‑prong pigtail to your trailer harness. Wiring follows the common color scheme so most owners can swap lights without rewiring the trailer.

• Drill a ~4.6-inch hole; grommet ring outer diameter ~5.3 inches
• White = ground, red = high brightness, black = low brightness
• Flush-mount design with supplied rubber grommets for a snug fit
• Standard 3-prong pigtails for plug-and-play compatibility

Are these lights durable enough for trailers, boats, and work trucks?

These lamps are built for outdoor vehicle use with a sealed lens and robust housing to resist dirt and splashes. The IP65 rating keeps out dust and heavy spray, and the LEDs tolerate vibration better than filaments, which is useful on rough roads or trailered loads.

• IP65 water resistance keeps out dust and road spray (not submersible)
• Solid-state LEDs withstand vibration and frequent on/off cycles
• Rubber grommets cushion the mount against movement and shock
• Designed for 8–16 V DC systems common on trailers and trucks

Who this kit is for: This Partswcgg 4-piece 4-inch LED set is aimed at trailer owners, RV and truck drivers, fleet managers, and DIY mechanics who want a reliable, energy-efficient lighting upgrade. It suits anyone replacing worn incandescent lamps, fitting new trailers, or upgrading reverse and signal lighting for better visibility during towing, parking, and highway driving. The included grommets and pigtails make it accessible to hobbyists while the sturdy LED design meets the durability expectations of commercial users.
