Turn the headlights on, and take the key out. Like you "forgot" to turn your headlights off when you got out of the car.
one little oversight on my part, i dont have the xenons and thought it would work with mine but when i did what you said, i saw that the part that lights up in your head lights does not in mine. Actually that part never lights up! not even when the car is on. Instead, when i do what you said, the left section, facing the right head light and the part thats not projector in your head light, lights up too bad i already ordered the M4 bulbs, DOH!
