It has a 40A relay, a 30A fuse, an on\/off button switch with indicators and a main line about 3 m (10 ft) long, and the supplier rates it for a maximum load of 280W. Easy Life Markets sells it in black as a single kit with a user manual, for anyone fitting extra lighting who would rather not build a loom from loose parts.\u003c\/p\u003e\n\n\u003cp\u003eThe reason to use a harness like this is the relay. A light bar draws far more current than a small dashboard switch should carry. So the switch only carries a small signal current, and that signal closes the \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Relay\" target=\"_blank\" rel=\"noopener\"\u003erelay\u003c\/a\u003e, which feeds the lights straight from the battery through the fuse. The cabin switch stays cool, the lights get full voltage and the fuse protects the circuit if something shorts. The supplier says all connectors, including the relay and its fuse, come pre-wired.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Is in the Kit\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x pre-wired harness kit (relay, fuse, switch and cables)\u003c\/li\u003e\n\u003cli\u003e1 x user manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe light bar itself, mounting brackets, cable ties and tools are not included.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e LED light bar wiring harness kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating voltage:\u003c\/strong\u003e 12V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay current:\u003c\/strong\u003e 40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse current:\u003c\/strong\u003e 30A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum load capacity:\u003c\/strong\u003e 280W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain line length:\u003c\/strong\u003e Approx. 3 m \/ 10 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch input line length:\u003c\/strong\u003e Approx. 90 cm \/ 35.4 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower source input line length:\u003c\/strong\u003e Approx. 50 cm \/ 19.7 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch:\u003c\/strong\u003e Mouse-style on\/off button with indicators and adhesive tape on the back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Copper wire and thermoplastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem weight:\u003c\/strong\u003e 429 g \/ 0.95 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging size:\u003c\/strong\u003e 21 x 10.5 x 8.5 cm \/ 8.3 x 4.1 x 3.3 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging weight:\u003c\/strong\u003e 432 g \/ 0.95 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e CJCZ26008640001\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat It Works With\u003c\/h2\u003e\n\u003cp\u003eThe supplier describes the kit as a universal fit for light bars, work lights, driving lights, spot lights and fog lights that run on a 12V DC supply. \"Universal\" here means it is not made for one vehicle, so there are three things to check against your own setup:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage.\u003c\/strong\u003e The kit is for 12V DC systems.

You have about 10 ft of main line to get from the battery area to the light, about 35 in to reach the switch position and about 20 in on the battery side.

Overloading them leads to hot wires, blown fuses and dim lights. A dedicated relay harness gives the lights their own fused supply from the battery and leaves the vehicle's original wiring alone, which also makes it easy to remove later.\u003c\/p\u003e\n\n\u003ch2\u003eWho This Kit Suits\u003c\/h2\u003e\n\u003cp\u003eOwners of 4x4s, pickups and utility vehicles with 12V systems who are adding a light bar or work lamps up to 280W, and workshops that fit auxiliary lighting and want a ready-made loom with the relay and fuse already in place.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCan I run two lights from it?\u003c\/strong\u003e The supplier does not state how many outputs the harness has.
