Using a control system for automatically switching power between a first light source attached to a welding shield pivotally mounted to an adjustable headband, and a second light source attached to the headband, a method for alternating power to the light sources includes steps (a) raising the shield to the uppermost rotational position resulting in power on to the second light source, the second light source remaining on at the raised position, and (b) lowering the welding shield to the maximum allowable distance resulting in power off to the second light source immediately followed by power on to the first light source, the first light source remaining on at the lowered position.
