XtremeVision H13 Bi-Xenon Relay Harness
This relay harness connects H13 or 9008 dual-beam HID bulbs directly to the vehicle battery for stable power delivery. It enables high and low beam switching through the factory socket without additional wiring to the battery. The unit is designed exclusively for 35W HID conversion kits and is not compatible with 55W kits. One harness operates both driver and passenger side headlights.
Thermal noise and power draw
The harness draws current straight from the battery to prevent HID bulb flicker during operation. No fan or active cooling is present, so the unit runs silently. Power consumption is limited to the 35W kit rating it supports. The relay handles high and low beam switching without introducing audible noise.
Build quality and connectors
The plug-and-play design uses the OEM socket for a direct connection that requires no cutting or splicing of factory wiring. A single harness serves both front headlights, reducing installation time and clutter. The compact form factor fits within standard headlight housings. The product carries a two-year manufacturer warranty.

Questions about this item
How do I install the XtremeVision H13-HARNESS-4-XT and what is the common mistake?
Connect the harness between the vehicle's OEM socket and the HID bulbs, then attach the relay to the battery for direct power; the step often missed is securing a clean battery-terminal connection to prevent flickering.
What maintenance or replacement will this harness need later?
The relay is a mechanical switch that can wear out after repeated high/low beam cycles; if beam switching becomes unreliable, replace the entire harness unit.
What limit appears first during sustained high-beam use?
The harness is rated only for 35W HID kits; running 55W bulbs will overdraw the relay and wiring, causing overheating or failure.
