<p>A road marker includes a transparent or translucent plate 70 that extends vertically. Light from an array of diodes (72) in the road marker is directed along the line 74 at an angle of between 6 and 8 DEG to the horizontal through the plate 70. Rays from the sun, illustrated by the line 78, will be reflected downwardly from the plate 70 and not back towards the driver. <IMAGE></p> |
