I think this post is more related to BMW owners than anything else, but if I'm in the wrong spot... Please move, or delete as fit!
I have a BMW E46 (2003 w/facelift) with xenon lights.
In Germany, there is no law about driving lights. In Norway, where I live, there is a rule. (Park lights at minimum in daytime, and driving lights when it gets darker).
The car have the the Automatic Lights option. The problem is, that at daytime.. there is no lights.. not at the front, and not at the back.
And if I drive through a tunnel, it ignights the xenons.
I have asked BAVARIA (BMW) if it's possible to reprogram the light units, so that when it's in automatic and it's daylight.
The park lights and bumper (fog) driving lights will turn on.
And ofcourse, when I gets darker.. automatically turn off the bumper lights and ignigts the xenons.
The answer I got where "We're not quite sure, but we think that it is impossible"....
Well, with a CarPC and Reslers I-BUS interface, it most defently would be possible. I've seen RR plugins and other standalone programs that can turn the whole car into a disco attraction! :lol:
Of you BMW owners out there... Any of you have done, or know if it's possible to do what I ask, with original BMW programing tool CarSoft?
Or is one "limited" to a CarPC?
And if this is the case, know of any plugins or background programs that can handle this for me.... (otherwise I need to make it myself, wich I kinda had hoped to not to). :)
Automatic lights use a light sensor. What about to cheat that?
A shutter with a simple lightbulb. It is enough to program the on/off state of it.
@bbalazs: Just covering the light sensor would cause the xenons to light up, as he described about driving into a tunnel, and he doesn't want that - just parking lights.
@Crinos: How do the BMWs with the Automatic Lights option that are legally imported/sold in Norway handle it? I would think that a car legally imported/sold in Norway would need to allow for the lights to come on in the daytime to comply with the law - even if that car had the automatic lights option. Or did this law go into effect after 2003 (when your BMW was manufactured)?
There is no difference in the cars sold in Norway, since one can just leave the lights "on" and then the xenons will light up when one start the car, and off again when one stop the car.

Did you solve your problem with the lights?
I have a BMW e46 2005 with the same automatic light swith.
I found this lighcontrol that allows you to program your lights: http://www.car-solution.de/vmchk/BMW...rd1=&keyword2=
But if there is possible to program the lights without having to buy that thing it would be great.
I just want to be able to have the swith on "auto" and during the day the parking and foglights are on and then when it gets darker the headlight go on.
