Headlamp (Hi) Circuit: Description

The high beam solenoid drives the mobile valve shade. And the mobile valve shade switches the high beam and low beam of headlamp.

• When the headlamp high relay is turned ON, magnetic force is applied to the high beam solenoid (1) by a current. The mobile valve shade (2) is switched to the high beam position.
• When the headlamp high relay is turned OFF, the current stops. The mobile valve shade returns to the low beam position automatically.
