ABSTRACT:
A mining machine having a tiltable and forwardly open scoop has a headlight mounted on the rear wall of the scoop and positioned to project a beam of light forwardly but along side a side wall of the scoop, no part of the headlight projecting above the machine. The headlight is mounted for sliding inwardly behind the scoop when a lateral obstruction is encountered but is biased to its outer position. An obstruction-engaging bumper link pushes the headlight inwardly. A linkage keeps the headlight beam horizontal when the scoop tilts.
