Each lamp contains 24 high-intensity red LEDs arranged to maximize visibility while using minimal power. The built-in flange makes surface installation straightforward, and the IP65 rating helps keep the lights working through rain, mud and road spray. These lights are designed for standard 12V systems and come wired for direct, reliable connections.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these lights perform as stop, turn and tail signals?\u003c\/h3\u003e\n\u003cp\u003eEach lamp uses a multi-function circuit so the same lens handles stopping, turning and running tasks. Bright LEDs provide clear signaling to other drivers, while a secondary lower-brightness mode preserves visibility for tail\/running functions. The arrangement and quantity of LEDs improve beam uniformity compared with a single bulb.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e24 super-bright red LEDs per housing for high visibility\u003c\/li\u003e\n  \u003cli\u003eDual-brightness functionality: higher for stop\/turn, lower for tail\u003c\/li\u003e\n  \u003cli\u003eConsistent light pattern that reduces dark spots at distance\u003c\/li\u003e\n  \u003cli\u003eSuitable for standard signaling wiring on trailers and trucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is involved in installing the flange-mount lights?\u003c\/h3\u003e\n\u003cp\u003eThe lights are flange-mounted for surface installation and require a single mounting hole in the vehicle body. The flange simplifies alignment and secures the light without needing an inset pocket. Installation uses a 3-wire hardwired setup: ground, stop\/turn, and tail power, making it compatible with common trailer wiring harnesses.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBuilt-in flange for simple surface mounting; no recessed cavity needed\u003c\/li\u003e\n  \u003cli\u003eApproximate mounting hole size: 4.38 inches diameter\u003c\/li\u003e\n  \u003cli\u003e3-wire hook-up: gray ground, red for high-brightness stop\/turn, green for low-brightness tail\u003c\/li\u003e\n  \u003cli\u003eEasy replacement for existing 4\" round trailer lights\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre these lights weatherproof and durable enough for heavy use?\u003c\/h3\u003e\n\u003cp\u003eThe housings meet an IP65 ingress protection rating, so they resist rain, dust and road spray commonly encountered in towing and outdoor work. The sealed lens and gasketed flange help prevent moisture intrusion, while LEDs provide long operational life with shock resistance compared to filament bulbs. The compact round design also minimizes exposure to impact from debris.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIP65-rated sealing against water jets and dust\u003c\/li\u003e\n  \u003cli\u003eSealed lens and flange gasket for dependable weather resistance\u003c\/li\u003e\n  \u003cli\u003eLEDs tolerate vibration and shock better than incandescent bulbs\u003c\/li\u003e\n  \u003cli\u003eLow-power operation reduces electrical load on 12V systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these fit my vehicle’s electrical system and bodywork?\u003c\/h3\u003e\n\u003cp\u003eThey are engineered for standard 12V DC vehicle electrical systems, making them compatible with most trailers, RVs, trucks, semis and utility vehicles. Confirm the mounting hole and wiring colors on your trailer before ordering; the set is ideal for retrofit or new installations where a 4-inch round housing is required.
