{"product_id":"h4-12w-led-warning-light-head","title":"H4 12W LED Warning Light Head | TIR Lens","description":"\u003cp\u003eThe \u003cstrong\u003eH4\u003c\/strong\u003e is a compact surface mount LED warning light head built around four 3W LEDs behind a TIR (total internal reflection) lens, giving a 12W LED array in a housing 25mm deep. It signals vehicle presence on traffic control, civil, utility and fleet vehicles, plant and machinery, and is supplied as a single fixed output per unit: white, red, or blue and red, selected at purchase.\u003c\/p\u003e\n\n\u003cp\u003eThe H4 surface mounts through two screw fixing points in the mounting ears, 104mm between centres, using 4mm screws. It suits grille surrounds, bull bars, guards, tray and body rails, headboards and rear body panels where a low profile head is needed. A moulded rubber surround sits around the housing to finish the head against the mounting surface. Confirm mounting hardware and wiring with your auto electrician for your specific vehicle and application.\u003c\/p\u003e\n\n\u003cp\u003eOutput runs across 19 selectable flash patterns through the TIR lens, and the head holds the last pattern selected when power is removed, so a fitted vehicle comes back on in the same setting. Input is 10 to 30V DC, covering 12V and 24V vehicles and plant with the one part, at a maximum draw of 9W.\u003c\/p\u003e\n\n\u003cp\u003eWiring runs on four cores: red for +12 to 24V DC power through a 3A fuse, black for chassis ground, white to set the head into flash group one or group two for simultaneous or alternating operation, and yellow for pattern selection and synchronisation. Connecting the yellow wires of several heads together synchronises their flash, and the manufacturer rates the H4 for synchronisation of up to 19 units, so a full set of front, side and rear heads can run as one system. Wiring should be carried out by a qualified auto electrician.\u003c\/p\u003e\n\n\u003cp\u003eThe housing is aluminium and polycarbonate, sealed to IP68 and rated for ambient temperatures from -20 to +65 degrees, suited to exposed mounting positions on vehicles working in vibration, dust and weather. LED lifespan is rated at 100,000 hours.\u003c\/p\u003e\n\n\u003cp\u003eSupplied product data lists ECE R65 XB1 00 0027 and ECE R10 03 12468. Vehicle lighting requirements vary by vehicle type, registration category and jurisdiction, so confirm the requirements that apply to your vehicle and use.\u003c\/p\u003e\n\n\u003cp\u003eThe H4 sits between the two other TIR heads in this range.
