Abstract

To improve design characteristics when the light fixture is turned on in a vehicle light fixture including a plate-shaped light guide. The plate-shaped light guide () is configured such that light from five light sources (AAAAandA) is totally reflected by a plurality of reflective elements () formed on a first plate surface () on a rear surface side of the plate-shaped light guide, and then emitted forward of a light fixture unit from a second plate surface () of the plate-shaped light guide. At that time, five light emitting regions (AAAAandA) are arranged at intervals in a horizontal direction in the plate-shaped light guide (), and then the reflective elements () are arranged in a state of being continuously side by side along a line L extending in a direction intersecting the horizontal direction in each of the light emitting regions (AtoA). Each reflective element () is formed in a substantially concave spherical surface shape. In addition, the light sources (AtoA) are configured to be able to be individually turned on in a state of being respectively arranged in the light emitting regions (AtoA).
