PURPOSE: To secure reliability of light distribution by reliably achieving a purpose by the other lamp even if a lamp runs into trouble. CONSTITUTION: In a light distrubution device for a vehicle to distribute the light from lamps to corresponding prescribed lights 21 to 29 through optical fibers 14 by collectively arranging plural lamps 1 to 9 in one place in an engine room of a vehicle, when a controller 123 detects lamp trouble on the basis of a switch signal from a switch corresponding to the light from the lamp, a light conductive passage switching unit 121 is controlled, and the optical fiber is switched, and it is backed up so as to distribute the same color light from the other lamp except the trouble lamp to a prescribed light, and light emission is reliably achieved. |
