They’re built to replace or upgrade factory reverse or tail lights on trailers, trucks, RVs, and work vehicles, offering two brightness levels for parking and reversing. Installation requires a 4.57\" mounting hole and a 3-prong plug; the lamps operate on 12V DC for wide vehicle compatibility.\n\n\u003ch3\u003eHow bright are these lights and what makes them effective?\u003c\/h3\u003e\n\u003cp\u003eThe lights use 24 high-brightness white SMD LEDs per lamp and a transparent lens to maximize light output and spread. Improved heat dissipation keeps the LEDs operating efficiently during extended use, producing consistent illumination for reversing and tail functions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e24 SMD LEDs per lamp for strong, even light\u003c\/li\u003e\n  \u003cli\u003eHigh-transparency lens for improved beam clarity\u003c\/li\u003e\n  \u003cli\u003eThermally efficient design to reduce lumen drop\u003c\/li\u003e\n  \u003cli\u003eVisible from behind for safer reversing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat mounting and electrical connections are required?\u003c\/h3\u003e\n\u003cp\u003eThese lights are designed for an easy flush-mount installation: cut a 4.57\" diameter hole and 1.89\" depth, fit supplied grommets, and set the fixture in place.
