I used a halogen (H4) with a modulator in my motorcycle for a long time. The decrease in tempeature caused a significant tungsten deposit to form on the inside of the quartz envelope. There was a significant hole in the low beam pool of light in front of the bike. I believe a dimmer defeats the halogen cycle.
