<p>A self-contained solar-powered illuminated reflector (20) provides improved visibility at a distance as a traffic safety aid. A housing (21) adapted to be secured to a highway or alternatively, to a vertical wall, encloses a reflector (32) for reflecting light in a predetermined direction toward highway traffic, a light source (40), a battery (50) and a photovoltaic system (36). The housing (21) includes a window member (34) for transmitting light outward from the light source (40) in the predetermined direction toward highway or pedestrian traffic. An optical lightguide (46) between the light source (40) and the window member (34) focuses the light from the light source so that the visible effectiveness of the light source is optimized. Circuitry (42) is provided for selectively enabling the operation of the light source for minimizing the power requirement to extend the useful life performance of the traffic marker.</p> |
