1. A lamp lighting control system for a vehicle, the lamp lighting control system comprising:
a turn lamp including a first light source;
a position lamp including a second light source;
an accessory lamp including a third light source;
a light-emitting face having a shape, wherein the light-emitting face is optically coupled with, and shared by, the turn lamp, the position lamp, and the accessory lamp such that light from each of the turn lamp, the position lamp, and the accessory lamp is uniformly distributed across the shape; and
a lighting control unit comprising one or more processors and one or more memories having programs, when executed, causing the one or more processors to be programmed to:
control lighting states of the turn lamp, the position lamp, and the accessory lamp;
turn off the accessory lamp in a case where the position lamp is turned on and the turn lamp is turned on; and
turn on the accessory lamp in a case where the position lamp is turned on and the turn lamp is turned off, and
wherein, when (1) the position lamp is turned on, (2) the turn lamp is turned on, and (3) the accessory lamp is turned off, the one or more processors are programmed to:
control the second light source of the position lamp to continue emitting light while the first light source of the turn lamp emits light; and
control a luminance of the second light source of the position lamp to decrease to a level that is lower than a luminance of the first light source of the turn lamp, but is not zero.
