Uh, I tested it with/without the low beams on. Even with the lights fully off (including parking lights) it ignited the high beam HIDs each time I pulled the stalk back. This seems like it'd be pretty detrimental to the lifespan of the HID system, not sure why BMW designed it this way.
Also, I dont have DRL but my inner pair of angel eyes are on as my DRL (I guess you could call that my DRL) I can do some more testing and make a video or something but to me it seems like it's just there for looks.
