  • Publication number: 20230354495
    Abstract: Systems and methods are provided for calculating, using an electronic processor, an average environmental brightness and determining a current pulse width modulation (“PWM”) output level provided to the light source. The method also includes determining, using the electronic processor, a target illumination level and a PWM adjustment rate. The PWM adjustment rate is based at least partially on the calculated average environmental brightness. The method also includes adjusting, using the electronic processor, the current PWM output level at the determined PWM adjustment rate to reach the target illumination level, and transmitting the adjusted PWM output level to the light source. The target illumination level is determined as a function of the current PWM output level and an output mode of the light source.
