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.
