Abstract: A lighting assembly has an elongated housing which contains a plurality of light emitting diodes that send light from one side of the housing. Connectors at the ends of the housing are provided to connect the lighting assembly into standard sockets of a fluorescent light fixture that has been modified to power the light emitting diodes. At least one of the connectors has a releasable holding mechanism that allows the housing to be rotated with respect to the sockets to aim the light is a desired direction and then hold the housing in that orientation.

Abstract: A lighting assembly for illuminating a vehicle interior has an elongated housing which supports a printed circuit board that has an electrically conductive pattern. A plurality of electrical terminals are connected to the electrically conductive pattern for coupling the lighting assembly to a source of electricity. A plurality of light emitting diodes are arranged in a plurality of rows on the printed circuit board. The light emitting diodes in each row being electrically connected in series between two of the electrical terminals. The light emitting diodes are so connected that application of electricity to selected ones of the electrical terminals causes illumination of different combinations of the rows of light emitting diodes which results in the lighting assembly producing different light intensity levels in the vehicle interior.
