BFKK 4 Inch Dual-Color LED Trailer Lights 24 LED Pack of 4

Dual-colour trailer lights

This pack contains four 4-inch round LED lamps that combine red stop, turn and tail functions with white reverse illumination in a single housing. Each unit uses 24 LEDs to produce both colours, so one fixture covers braking, signalling, running lights and backup duties. The IP67 rating confirms the lights are sealed against dust and water ingress for trailer, truck or utility-vehicle use.

Replaces separate stop-tail and backup lamps

Instead of mounting a dedicated red lamp and a separate white backup light, these dual-colour units handle both jobs from one 4.5-inch cut-out. The upgrade is worthwhile when you want to reduce wiring runs and hole cuts on a trailer refit, or when an older incandescent pair has failed and you prefer a single sealed LED assembly.

Simple three-wire pigtail fit

Each light ships with a standard three-prong offset pigtail and a rubber grommet; white wire is ground, red wire drives high-brightness stop/turn, black wire drives low-brightness tail, and the extra yellow wire powers the white reverse function. Drill a 4.5-inch hole, seat the grommet, press the lamp in and connect the pigtail — the only common issue is forgetting the yellow wire, which leaves the backup function dead.
