Abstract

See full text

A vehicular lamp can enhance the impression of the direction indication due to the movement of light when performing sequential winker controls by sequentially turning off a plurality of light-emitting parts. A lighting control device for performing lighting control of the vehicular lamp including the plurality of light-emitting parts, includes processor circuitry configured to perform controls to repeat a lighting cycle including turning on the plurality of light-emitting parts and maintaining a lighting state of all the light-emitting parts, and then sequentially turning off the light-emitting parts in a predetermined direction with a time difference and maintaining a lights-out state of all the light-emitting parts in such a manner that a rise time from the lights-out state to the lighting state during energizing the light-emitting parts is made longer than a fall time from when the lighting state to the lights-out state during deenergizing the light-emitting parts.
