PRINCIPLES OF OPERATION

The headlamp system is a dual-beam pattern system. It consists of a low and high beam headlamp, with a replaceable bulb. The headlamp assembly has the park/turn indicator lamp integrated into the headlamp assembly. The headlamp switch routes voltage to the headlamps, the parking lamps and the autolamp system when demanded. All exterior lighting devices require between 11.3 and 14 volts for the lamps to illuminate correctly. An exterior lamp that appears to be dim may be caused by voltage that is below this level.
