The set of four arrives with rubber grommets and three prong wire pigtails for straightforward installation, and the standout feature is the dual-color 19 LED array that switches to white when reverse is engaged, making it a useful combo for trailers and trucks.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-color 19 LED array:\u003c\/strong\u003e The same LEDs produce red for stop\/turn and white for reverse, simplifying wiring and conserving mounting space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlush mount with rubber grommet:\u003c\/strong\u003e The included grommets create a clean, sealed installation and help reduce vibration damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-prong wire pigtails plus auxiliary plug:\u003c\/strong\u003e Standard wiring plus an extra blue male bullet plug for the reverse function makes hookup compatible with most trailers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 waterproof rating:\u003c\/strong\u003e Sonically sealed and submersible construction protects the LEDs in wet or harsh weather conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact dimensions:\u003c\/strong\u003e At about 5.1in diameter and 1.1in height overall, these lights fit tight mounting locations when a 4.5in hole is drilled.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is best for owners of trailers, utility vehicles, pickup trucks, flatbeds, and small commercial vehicles that need a compact combined stop\/turn and reverse lamp.
