ABSTRACT:
A lighting system for a grain auger which enables grain bins to be loaded at night including a light bar mounted on an elongated grain elevator or auger in spaced relation to the grain bin being loaded and in spaced relation to the hopper end of the grain auger which receives grain from a grain conveying body mounted on a vehicle. The light bar includes separate light units to illuminate the grain bin and the hopper end of the auger for effectively illuminating the work area associated with a grain storage bin or grain drying bin and the hopper end. The light units are adjustable for optimum positioning in relation to the work area with the adjustment of the light units also enabling the light to be directed to the open cover at the top of the bin or at the ladder on the side of the bin. The light bar is mounted by a split clamp having cushioning material on the interior thereof to enable the light bar to be clamped to the grain auger housing without damage and in a secure and adjustable manner. The light units are standard halogen lights powered by the battery of a tractor or other suitable DC power source with the electrical conductors supplying electrical energy to the lights being positioned along the bottom surface of the grain auger.
