It sounds like the bulb is drawing too much juice. Perhaps you could replace the incandescent bulb with LED which draws a lot less. These little motors don't produce a lot of juice, but there are ways around it. I've rebuilt a number of headlights and replaced the bulbs with LED lights. Do a search and you'll find more information here on how to's.
