BMW 3 series (e.g. BMW E90) uses H7 bulbs, one each for high and low beam. When they are switched on, are the power consumption different for high and low beam or are they same? That is to say, does BMW modify the power consumption (and there by modify out put) of these bulbs when using for high and low beam function?
There is a thread in a BMW forum asking the same question and it has created a sort of disagreement. My opinion is that the power consumption is the same but the light output is modified by the reflector. A gentleman who has worked for the BMW suggests that they are modified by the BMW.
Can some one please enlighten us?
