ABSTRACT:
A protective, reflective, light diffusing sleeve is adapted to mount on a light element to protect the element and intercept light emitted therefrom. The sleeve comprises a tube adapted to telescopically receive the element and a reflecting member carried by the tube for reflecting light emitted from the element. The tube is adapted to mount on the element for free rotation relative thereto to move the reflecting member about the element to control the direction of reflective light. The sleeve further comprises an element carried by the tube opposite the reflecting member for diffusing light reflected therefrom. The diffusing element comprises a field of prisms formed on and extending along a longitudinally extending portion of the tube.
