摘要： To improve pedestrian visibility. Provided is a headlight controller connectable to a first headlight and a second headlight spaced apart in a vehicle width direction at the front of the vehicle, the headlight controller including: a rainfall amount detection means installed in the vehicle; and a controller installed in the vehicle, where the controller is connected to the rainfall amount detection means, and the controller carries out control such that when rainfall amount detected by the rainfall amount detection means is equal to or more than a predetermined value, irradiation light from the first headlight becomes relatively darker than irradiation light from the second headlight.

摘要： Provided is a vehicle signal light in which a person with protanopia (p-type color vision deficiency) can perceive whether or not the vehicle signal light, e.g., a stop lamp, a tail lamp, or the like, is turned on. The vehicle signal light includes a first light source configured to emit red light and a second light source configured to emit amber light. The first light source and the second light source are simultaneously turned on and are configured to emit light with a higher luminous intensity in response to a braking operation, and the emission intensity of the first light source is higher than that of the second light source.

摘要： 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.
