摘要:
A road indication device is provided. The road-guidance indicating device has a light projection unit including light control means for controlling a lamp and light emitted from the lamp. The light projection unit project a light whose peak luminosity is 30000 cd or more, i.e., the light has a luminosity equal to or larger than a peak luminosity of a headlight of a car running on the road. Since a light pillar of light having a high light output and a thick light pillar is projected from the light projection unit, the visuality of the light pillar is improved even in the bad weather and the boundary between the driveway and the shoulder on the road can be affirmatively guided and indicated.
