Abstract:
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.
