Abstract: A light system including a first light source, a second light source, a first drive device configured to supply a first pulse-width modulation current for supplying power to the first light source, the first current including a first peak intensity and a first duty cycle, a second drive device configured to supply a second pulse-width modulation current for supplying power to the second light source with the second current comprising a second peak intensity and a second duty cycle, a control module generating a first control signal and a second control signal for the first control device and the second control device. The first peak intensity being lower than the second peak intensity, and the first duty cycle is higher than the second duty cycle.
