A light that mounts to the back of the hand by a band. A housing has a narrow beam lamp and the wide beam lamp with a corresponding lens system to form a light beam with the desired divergence. A number of power control configurations are contemplated, including separate on/off switches, multi-position switches, luminosity level switches with a master on/off switch, and a single switch for each lamp that cycles through several luminosity levels. Power is supplied by batteries. The band includes a bracket attached to the housing and a strap that permanently or removably attaches to the bracket, the combination of which encircles the hand. The light includes mechanisms for adjusting the housing relative to the band.
