摘要： A light source driving circuit for powering multiple light sources in a vehicle includes multiple current limiters and a balance controller. The current limiters are coupled to the light sources for adjusting currents of the light sources respectively. The balance controller coupled to the current limiters can control the current limiters such that a current flowing through each of the light sources is substantially the same as a first target current. Moreover, the balance controller can control the current limiters in response to a brake of the vehicle such that a current flowing through each of the light sources is substantially the same as a second target current.
