Lighting systems for emitting light in multiple directions including one or more light emitting devices and a housing configured to receive the one or more LEDs are provided. An energy generator produces energy to neutralize environmental danger. A pair of plastic side members and a pair of plastic end members are attached to the base member. Changes in the electrical resistance of the electrode facilitate a display on the visual indicator including changes in color or brightness. Also disclosed are pharmaceutical compositions containing one of the compounds described above. The circuit for torque measurement provides the torque detection data based on the transmitted differential signal and at the same time extracts the offset voltage to use it for the failure diagnosis.
