  6.  
  7. Check the operation of the switch. Turn the ignition key to ON , but do NOT start the engine. Have an assistant observe the brake lights at the rear while you push lightly on the brake pedal. The lights should come on just as the brake pedal passes the point of free-play.

  9. Adjust the switch as necessary to get the correct response from the lights. The small amount of free-play in the pedal should not trigger the brake lights; if the switch is set incorrectly, the brake lights will flicker due to pedal vibration on road bumps.
