The no. 1 headlight ECU sub-assembly LH and RH illuminates the LED used as a light source for the low beam headlights, high beam headlights and clearance light. When the low beam headlights or high beam headlights are illuminated, a constant current flows to the LED to instantly stabilize the headlights. Also, changes in the LED current due to fluctuations in the voltage are reduced to prevent the lights from flickering.
The no. 1 headlight ECU sub-assembly LH controls the automatic headlight beam level control system or adaptive high beam system.
