I was playing around with the headlights on my new 330i tonight and noticed that both the low and high beam Xenons are on the outside two lights (via two bulbs in the same light) of the four headlights. The inside two lights look like they are halogen not Xenon but they only light up when I pull the turn signal/lights stalk to flash the lights. They don't go on with any other setting. So naturally I figured that they might be daytime running lights that need to be enabled by the dealer (as has been the case in the past) but I checked the manual and the section on DRL just says to turn your low beams on for DRL's. What am I missing? What's the purpose of these extra headlights. I can't image they were put on just to flash oncoming drivers.
