Stoplight
General Description
The circuit consists of the stoplight, stoplight switch
(vehicles w/o cruise control), brake switch (vehicles
w/ cruise control).
With the brake pedal depressed, the stoplight switch
or the brake switch is turned on to illuminate the
stoplight. The brake switch controls not only the
operation of the stoplight but also the input of the
cruise cancel signals to the cruise control unit.
