Lighting of earthmoving equipment is discussed with emphasis on providing adequate illumination for the rubber tired hauling units. As the vehicle speeds increase, the lighting problem be comes more critical. The techniques used to evaluate sample lighting arrangements are discussed.
Service life of the 12 and 24 volt lighting elements is also of concern in the severe operating requirements imposed by earthmoving applications. Increased life can be obtained by using elements and lamp housings designed for off-highway equipment.
