Headlight dimmer switch for Nissan Almera Classic

By turning the knob, depending on the load of the car, the angle of inclination of the headlight beam is changed in such a way as to prevent dazzling of oncoming drivers. Alignment of the mark on the handle and the number on the scale ensures the appropriate adjustment of the position of the headlights for the following vehicle loading options:

• 0 - one driver or driver and passenger in the front seat;
• 1 - all places are occupied;
• 2 - one driver and cargo in the trunk;
• 3 - all seats are occupied and cargo is in the trunk.
