The reason BMW does not have to, is because the inner bulbs do not light up when the high beams are 'on' on xenon equipped cars right? You can run the high beams (inner bulbs all day) on Halogen assemblies because the light and reflector are built differently. The inner bulbs light up on Halogen equipped cars.

Then again I maybe totally wrong as the OP has a LCI car and it maybe totally different on these cars.

Does the OP have a Halogen equipped car or Factory xenon?

 

The LCI halogen headlights does have halogen reflectors even thought he low beam is projector. So in theoretical terms, the heat dissipating from the HID of 35w should still be lower than the 50-55w that a stock halogen bulb produces.

The inner bulb for the LCI xenons, I believe act as cornering lights, and since they're bi-xenon, there's no separate bulb from the low beam. Given what the OP has said so far, it sounds like he has LCI halogens.

 

I wonder if a simple jumper and a diode from the fogs to the inner lights (high beams) would do what the OP is asking for.

Then the OP would be constantly getting flashed by people being blinded

 

In theory that should work, so when he turns on the fogs, his high beams will be on. Obviously the downside is that he can no longer turn off the high beams whenever his fogs are on.

Additionally, I am not sure what the long term effects might be drawing that amount of current from that circuit.

 

Or you could wire it the other way around, that way whenever the high beams are on the fogs are on. Then if you want just the fogs you can just turn on the switch to the fogs. This is of course if the inner lights go on when the high beams are on.

 

Lol, true. It's too much work in my mind. Much easier to just code the damn thing. Cleaner and faster.

 

yeah if you have a device to code with!

Maybe later this year if I'm too bored and have some extra cash. Otherwise I'd just have you come over.

 

Can someone tell me step by step how to do it? I don't feel like paying 150 for it lol
