Roadvision RBWK LED Light Bar Wiring Harness Kit 12V 24V Plug Play
A complete second generation plug and play wiring harness kit for one LED bar light, the Roadvision RBWK features smart electronics that automatically detect positive and negative switched headlamp systems, an H4/HB3 piggy back connector, waterproof Deutsch plugs, supplied 12V and 24V relays, and an illuminated rocker switch.
Product Overview
The Roadvision RBWK is a second generation bar light wiring kit fitted with smart electronics that automatically detect positive and negative headlamp systems. This removes the guesswork from modern vehicle installations, with the simple plug and play system compatible with halogen, HID, and LED headlight bulbs without the need for complex wiring modifications.
The kit provides everything needed to wire one LED bar light, connecting to the vehicle's high beam via the H4/HB3 piggy back connector so the bar switches with the headlights. Waterproof Deutsch plugs keep the connections protected in the engine bay and behind the bar, and the kit is supplied with both 12V and 24V relays to suit either vehicle system, plus an illuminated rocker switch for in-cabin control. Fitment is a simple DIY job following the supplied wiring diagram.
