Narva has a complete "Plug n Play" driving light wiring harness designed to be used with any halogen or HID driving lamps. Installation is easy and the harness comes supplied with additional female waterproof connectors and joiners for fitment to driving and fog lights of any brand or type. The kit includes an off/on mouse switch, 30A fuse, waterproof fuse holder, a relay and relay block. Connections are protected with heat shrink and cables are insulated with corrugated tubing. A special feature of the harness is the patented switching box that allows the harness to work on either positive or negatively switched vehicle wiring, eliminating the difficulty associated with modern headlamp circuits. Simply slide the switch to test the harness and lamp operation.
