I heard long ago when HID's started coming around with the growth of Xenon equipped vehicles, that turning them on and off (non normal operation) within short periods of time greatly reduces the life of the bulbs. Also to not turn on off more than 8 times within any given short interval. All xenon/hid systems require that the gases in the bulb warm up to maximum brightness, however quick or not, that may be. Most bi-xenon factory headlights are put into high mode by the lens articulating or the fixture moving in some way allowing the beam to shift and more light directed. As long as you don't have a set of lows and a set of highs where you're lows run for your main beam of course, and flicking on/off the high bulbs you're ok. Use a q-beam next time....much more fun!
