Thumbs up DIY: Wiring Halos to "Parking Lights"

You won't find this info anywhere else...

Many of the instructions out there tell people to wire their halos trigger wire to either the ECU or the fogs.

The problem with wiring the halo to the ECU is that they are on whenever the car is on. It's like driving with fog lamp on in broad day-light. Pretty Ghetto... Isn't it? So, whenever you want to turn it off, you'll need a separate switch to turn it off.

Also, when you wire the halos to the fog lights, you can not turn on the halos with the fogs being off. I would want a bit more flexibility than that.

One method of wiring that these halo vendors don't provide in their instruction is "How to wire halo to the parking lights." You simply can not tap into the corner marker in the front. This is because the corner marker uses a single filament bulb for parking and flasher. So to make this bulb into a dual purpose bulb, bmw send 6V for parking and 12V for flasher. If you were to wire your trigger wire here, your halos will flash whenever you turn on the turn signal. Also, parking light is how BMW wires their OEM halos. The cool thing is that when your auto headlight turn on your parking, your halos will turn on with it.

So now the question is "Where should I tap into?" So here it is....

BTW, If you find this useful, add to my Rep by clicking on this icon on the left...THX

Default Step 1

1. Remove the kick panel underneath the steering wheel.
2. Look underneath the dash and locate the wire going to your Light Control Module.

If you don't know what a LCM (Light Control Module) looks like, it looks like this....

Default Step 2

Cut open the bundle and locate the following wire.... This is the wire that you'll need. Tap your trigger wire into this!!! And then you're done!!!

This wire goes to the driver side tail lights assembly. The benefit of tapping into the LCM is that you don't have to run a wire to the back of your car. I don't know if this wire is the same color for the LED tail-lights.
