  example of use    
    The headlight dHSR can be used on loaders and drilling jumbos.
Its special concept is to reduce the blinding in underground use, by switching from high to low beam and addional dimming.
   distinguishing marks    
    The engine driver on a loading mashine can reduce the blinding of the headlights by switching and dimming from high to low beam with a small switch on his monitoring panel.
The dimming- and temperature-controle function of the headlight dHSR is arranged by an monitoring electronic in the transformer which send its signals to a switching element in the motor control unit dMS 150/m.
The electronic in the transformer also monitors the temperature inside the headlight and reduces the electrical power when reaching the limited temperature.
