Built with 16AWG wiring and a power relay, it supports dual fixtures up to a combined 180W on a 12V system and includes extra blade fuses and a clear wiring diagram to simplify installation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat bulbs and vehicles will this harness work with?\u003c\/h3\u003e\n\u003cp\u003eThe kit is made for common fog-light sockets and accepts 9005, 9006, 9012, 9140, 9145, 9150, 9155, HB3 and H10 style fog bulbs. It specifically does not fit H11 sockets, so verify your bulb type before purchasing. The harness is intended for 12V systems; if your vehicle runs 24V you will need a matching 24V relay.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible sockets: 9005\/9006\/9012\/9140\/9145\/9150\/9155\/HB3\/H10\u003c\/li\u003e\n  \u003cli\u003eIncompatible: H11 bulb connectors\u003c\/li\u003e\n  \u003cli\u003eVoltage: Designed for 12V; replace relay for 24V systems\u003c\/li\u003e\n  \u003cli\u003eMaximum combined load: 180W for both outputs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the wiring harness protect the electrical system?\u003c\/h3\u003e\n\u003cp\u003eProtection is handled with a power relay plus blade fuses to guard against over-current and short circuits. The included fuse holder accepts a blade fuse and the package ships with two spare fuses.
