How do I wire a LED light bar to my high beams? (1 Viewer)

[Jeff Cooper]

I am thoroughly confused by what people say that the power for the high beams is actually on the ground side(?)

Can anyone tell me what wire I need to connect the “hot” wire of my light’s wiring loom to in order to get the light bar to work only when my high beams are on?

Thanks in advance!

A SwitchPro 9100 is a very clean setup for all your accessories in a small package. Not the cheapest way to go however.

It’s not difficult to connect the light bar. Here’s a video to help. I like the 3 position switch they use to allow independent option of the light bar.

How do I use High beams as a trigger for my aux lights?

My goal is to use a relay to power my aux lights while using my high beams as the "switch". I wired everything up correctly but using my voltmeter I get 12 volts on my high beam side both when high beam is triggered, and when high beam is off my volt meter still reads 12 volts on the high beam...

Off Road/driving lights wiring question

So I picked up some cheap Hella lights. Trying to get them wired up. Diagram shows you have a line going from the switch and tapping into the high beams. Does it matter which line on the high beams you tap into? 2 wires coming off the high beam socket are a red with blue stripe and a red...

My attempt at making aux lamps work with high beams or low beams, as I got tired of fumbling for a switch in the dark with oncoming traffic.

You are confused because that's not how it works.
The high beams are a switched ground. There is +12 feeding one side of the high beam lamps and they are activated by grounding the other side through the stalk switch.
This is all explained in the factory service manual and EWD which you can download from the resources section.

You need to add a relay. Hook it up as normal except pull the ground from the ground wire up near the headlight. When you trigger the lights it will close the ground and cause your relay to activate turning on the light bar. Run the trigger wire (normally use 12v+) for the relay to a switch in the cab so you can override the light bar being on/off when the high are on.
