Abstract
A pair of lamps are mounted on either side of a protective helmet on indexing tables that permit each lamp to be independently directed at a different target. Each lamp table is slidably received within a base section so that the lamp can be easily removed from the helmet. A utility band passes between the two base sections and is held therebetween by gripping bars mounted in each base section. The band is adapted so that articles can be carried thereupon.
