Abstract
A vacuum cleaner headlight system incorporating a light pipe is provided. The light pipe includes reflex optics to control the distribution of light across the width of the output edge of the light pipe, as well as to prevent light from escaping through the sides of the light pipe. A reflex optical reflector is also part of the system, for reflecting light from a light bulb into the light pipe without requiring a metallized mirror.
