Yes but you can't quickly flash an HID bulb. The ballast's need to have some warm up time. Without that the ballasts like to die. You can turn on your lights, wait 10 seconds, and then flash, then turn them off. Or just have a halogen bulb and flash that way. Its why the OEM's have been so reluctant to run Bi-xenon's. I've seen more and more cars with highbeam and lowbeam projectors, but I imagine the high beam bulbs are halogen while the low beam is HID.
