Designed specifically for Holden WB models including Ute, One Tonner, Panel Van and Statesman, this Headlight Wiring Loom Harness \u0026amp; Relays kit upgrades your lighting system by delivering power straight from the battery through dedicated relays. Relay-Boosted 12V System: Designed to optimise lighting performance by supplying direct battery voltage to the headlights.Dual Relay Configuration: One relay for Low Beam, and One relay for High Beam, Ensuring stable voltage delivery and balanced load handling.Plug N Play Design: Connects directly into existing factory headlight connectors, which act as trigger signals for the relays. No permanent modification to original wiring required.Maximum Light Output: Eliminates voltage drop caused by ageing, thin factory wiring, headlights burn whiter and brighter — even with standard globes fitted.Switch Preservation: The factory WB headlight switch is a known weak point. This system reduces the switch’s role to a low-current trigger, dramatically extending its lifespan.Integrated Fuse Protection: Fused power supply protects the new circuit and vehicle electrical system.Period-Correct Connectors: Uses colour-matched plugs to maintain a factory-style appearance under the bonnet.For Holden owners wanting brighter, safer night driving and protection for their hard-to-find headlight switch, the Headlight Wiring Loom Harness \u0026amp; Relays offers a smart, reversible upgrade that improves performance without compromising originality.","brand":"Auto Recreations","offers":[{"title":"Default Title","offer_id":41873005215838,"sku":"WK1552","price":229.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/0587\/7086\/files\/WK1552.jpg?v=1776195299","url":"https:\/\/checkout.kingswoodcountry.com.au\/products\/holden-wb-headlight-wiring-loom-relays-plug-n-play-wk1552","provider":"Resto Country Spares","version":"1.0","type":"link"}
