Manufactured with very high-quality 16 AWG copper wire, it will be able to handle up to 15A or 300 Watts at 12Volt DC.  Which is more than enough to handle a 70" High Power Luminix Light Bar producing 27,000+ Lumens (that was just for quick reference).Each kit includes a heavy-duty relay that connects directly to your vehicle's battery, keeping your factory electrical system 100% safe and intact, but it also protects your expensive Light bar and battery via the in-line fuse that connects right before the battery terminal for easy access in case of an overcurrent or short circuit. Also included with each kit is our LED Lighted Switch, easily alerting you if the power is ON or OFF right inside your vehicle. But If you prefer to go wireless instead of finding a place to install a switch, you can add this wireless remote< to this harness in just a few seconds!Each harness comes with all the necessary hardware to install and step-by-step instructions,  designed by Putco Inc.
