PURPOSE: A car headlamp system for controlling uniform roughness is provided to drive by identical voltage by controlling a varistor until voltage of a left headlamp becomes to be equal with voltage of a right headlamp. CONSTITUTION: Variable terminals of varistors(11,12) outputting voltage corresponding to change of resistance connect with head lamps(13,14). A resistance corrector(15) changing output voltage from variable terminals of the varistor into same resistance connects with left and right headlamps. The headlamp emits light of identical voltage by inputting voltage value changed equally from the resistance corrector. A car headlamp system for controlling uniform roughness improves durability by spending equivalent power by driving the left and right headlamps by same voltage by having a variable resistor within.
