发明名称 Light attenuator for high/low beam vehicle headlight bulb
摘要 A light attenuator sleeve which removably attaches to a high/low beam halogen vehicle headlight bulb. The sleeve is designed to fit onto the high/low beam bulb assembly so that light emitted by the bulb passes through the sleeve and the intensity of the light is attenuated. The sleeve is attached to the high/low beam bulb assembly after the low beam filament is expired and has an appropriate degree of opaqueness to attenuate light emitted by the high beam filament to a low beam intensity after passing through the sleeve.
