It comes with a 12-volt relay, an on\/off switch, an ATP connector, and a 30 amp inline fuse. Wire it in once and your auxiliary light gets full battery power without cooking a dash switch.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eAdding an Optilux LED light or light bar to your rig is the easy part. Wiring it so it gets full power and doesn't fry a switch is where people get stuck. That's exactly what this Hella Optilux Sport harness is built for. It's a complete 12-volt wiring kit for one LED light or light bar drawing up to 300 watts, and it takes the guesswork out of a clean install.\u003c\/p\u003e\n\u003cp\u003eHere's the thing about a 300-watt light. At 12 volts, that's right around 25 amps of current. No dash switch is meant to carry that kind of load directly. Run it through the switch anyway and you'll melt contacts, dim the light, or worse. So this harness uses a relay. The switch only carries a tiny trigger signal, and the relay does the heavy lifting, feeding the light straight from the battery through heavy-gauge wire. That's the right way to wire an auxiliary light, and it's how every serious install gets done.\u003c\/p\u003e\n\u003cp\u003eThe relay and switch are what make this more than a length of wire. A relay is a simple electromagnetic switch. Send it a small signal from the dash and it snaps closed, handing the light a full, direct feed from the battery. That keeps voltage up at the light so you get every lumen it's rated for, and it keeps the high current out of your dash. The included on\/off switch wires into that trigger circuit, so flipping it on and off is all you deal with day to day.\u003c\/p\u003e\n\u003cp\u003eEverything you need is in the box. You get the 12-volt relay, an on\/off switch, the ATP connector that plugs into your Optilux light, and a 30 amp inline fuse already in the power lead. The fuse sits close to the battery and protects the whole circuit. If something shorts out down the line, the fuse blows first and nothing else does. No hunting for parts at the store halfway through the job.\u003c\/p\u003e\n\u003cp\u003eThe install is straightforward if you've done any 12-volt work before. Run the fused power lead to your battery's positive terminal. Ground the relay to clean, bare metal, not a painted surface, so it triggers reliably every time. Mount the switch somewhere you can reach it from the helm or the driver's seat. Then plug the ATP connector into your Optilux light and you're done. It's an afternoon job, and you don't need to splice into any factory wiring.\u003c\/p\u003e\n\u003cp\u003eThis harness handles one light or one light bar, up to that 300-watt ceiling. Before you wire in, check the wattage or amp draw of your light. As long as it's at or under 300 watts, you're in the clear. If you're running a pair of lights, you'll want a harness per light or a setup rated for the combined load. Don't try to daisy-chain two big bars onto a single 300-watt harness and hope for the best. Match the harness to the light and it'll run trouble-free.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone bolting on an Optilux driving light, fog light, or LED bar who wants it wired right the first time. Boat, truck, side-by-side, or work rig, the electrical principle is the same. The ATP connector is made to mate with Optilux lights, so there's no cutting and crimping a custom plug. If you already run Hella Optilux lighting, this is the harness designed to go with it.\u003c\/p\u003e\n\u003cp\u003eOne more tip from experience. Give the connections a shot of dielectric grease before you button everything up, especially any exterior plug. It keeps moisture and corrosion out of the pins and keeps the circuit happy for the long haul. And take a minute to route the wiring away from sharp edges and hot spots. Use the existing chase tubes or looms if your rig has them so nothing chafes through over time. Little things like that are what separate a five-minute job from a five-year job. Do the wiring right, fuse it properly, and let a relay carry the load. This kit puts all of that in one bag.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e12-volt wiring harness for one LED light or light bar up to 300 watts\u003c\/li\u003e\n  \u003cli\u003eIncludes a 12-volt relay so high current bypasses your dash switch and feeds straight from the battery\u003c\/li\u003e\n  \u003cli\u003eOn\/off switch wires into the low-current trigger circuit for simple day-to-day control\u003c\/li\u003e\n  \u003cli\u003eATP connector plugs directly into Optilux lights, no custom crimping required\u003c\/li\u003e\n  \u003cli\u003e30 amp inline fuse sits in the power lead to protect the whole circuit\u003c\/li\u003e\n  \u003cli\u003eHeavy-gauge power feed keeps voltage up at the light for full brightness\u003c\/li\u003e\n  \u003cli\u003eHandles up to 300 watts, matching Optilux driving lights, fog lights, and LED bars\u003c\/li\u003e\n  \u003cli\u003eComplete kit with everything needed to wire one auxiliary light in an afternoon\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Hella Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhy does this harness use a relay instead of just a switch?\u003c\/summary\u003e\n    \u003cp\u003eA 300-watt light pulls about 25 amps at 12 volts, and no dash switch is built to carry that directly.
