Abstract: A vehicular light source system includes: first and second laser emitters configured to emit first and second lasers; a thermometer configured to measure peripheral temperature; and a light source controller. The strength of the first laser at a temperature lower than a threshold temperature is higher than that of the second laser at that temperature. The strength of the first laser at a temperature higher than the threshold temperature is lower than that of the second laser at that temperature. The light source controller is configured to control the first and the second laser emitters such that: the strength of the first laser becomes higher than that of the second laser if the peripheral temperature is lower than the threshold temperature; and the strength of the second laser becomes higher than that of the first laser if the peripheral temperature is higher than or equal to the threshold temperature.

Abstract: This dirt detection system is composed to detect dirt attached to an outer cover of a lighting tool for a vehicle. A camera, a LiDAR unit, and a millimeter wave radar, which detect the surrounding environment of the vehicle, are each mounted on the lighting tool for a vehicle. The dirt detection system is provided with: a thermal imaging camera composed to acquire thermal image data showing the outer cover; a lighting tool cleaner composed to remove the dirt attached to the outer cover; and a lighting tool cleaner control unit composed to determine, on the basis of the thermal image data, whether the dirt is attached to the outer cover and to drive the lighting tool cleaner in response to the determination that the dirt is attached to the outer cover.
