High Beam Indicator

The high beam indicator gives an indication to the vehicle operator when the headlamp high beams are illuminated, or when the exterior lamps are inadvertently left On. This indicator is controlled by a hard wired input from the headlamp beam select switch circuitry of the multifunction switch to the cluster, and by the instrument cluster electronic circuit board based upon cluster programming and hard wired inputs from the head/park/fog lamp switch circuitry of the multifunction switch, the driver door ajar switch, and the ignition switch. The high beam indicator bulb is grounded on the instrument cluster electronic circuit board at all times. The bulb will be illuminated anytime the headlamp high beams are turned on, regardless of the ignition switch position. The bulb only illuminates when it is provided battery current by the beam select switch circuitry of the multifunction switch, or by the instrument cluster electronic circuit board. The instrument cluster will turn on the high beam indicator for the following reasons: beam select switch input, and exterior lamps-on optical warning,
