Plug and Play Quick Fit to High Beam Wiring Harness

Quick Fit & High Beam Single Driving Light or Light Bar Wiring Kit Loom.


Plug & Play Wiring Harness for Quick Fit installation of your driving lights. The supplied H3 (HB3) and H4 Adapters trigger your driving lights from your high beam without cutting or soldering any wiring.  Simply unplug your HB3 or H4 connector at the back of your headlight's bulb, plug in our adapter and you're done! Driving lights will only trigger from a high beam, and the switch will act only as an isolator.  

Our new V2.0 has built-in electronics that automatically detects whether your system is positive or negative switched, and will work right out of the box without any modification whatsoever. Toyota's, Ford Ranger, Mazda BT50 among many other popular 4x4 are notorious for being very difficult and costly to wire driving lights to high beam, our quick fit harness takes all the guesswork out of it. 

Contains everything you need to get your lights connected:  ON/OFF Switch, 60A Relay, 30A Fuse, ribbed cable protectors, heat shrink wrapped relay.

    Ranger light bar

    I purchased this harness over the cheaper eBay ones and am very pleased I did. Instructions were great with videos on the Stedi website. The install went very well with no issues. I purchased the wiring adapter from Stedi as it wasn't available here at the time of purchase. Time to try the light after the install and bingo, worked perfectly. Very happy I went with this harness as it is of superb quality. Cable lengths were just right without too much excess to bundle up
