Dimmer Switch: Description and Operation

The light/dimmer/turn signal combination switch lever, located on the left side of the steering column, controls the operation of both low beam and high beam headlamp operations. With the headlamps activated, pushing the lever forward into the detent position changes the headlamps from low beam to high beam operation. Pulling the lever back to the center position will return the headlamps from high beam operation to low beam operation.
