Patent ID: 7360911

Claim:
An oscillating signal light apparatus comprising: a signal light having a signal light axis, the signal light being movable about the signal light axis; a driven member having a driven member axis, the driven member being movable about the driven member axis, the driven member being operatively connected with the signal light to cause the signal light to move about the signal light axis in response to the driven member moving about the driven member axis; a drive member having a drive member axis, the drive member being movable about the drive member axis; a first belt having a length that is not a continuous loop and has opposite driven and drive ends, the first belt driven end being secured to the driven member and the first belt drive end being secured to the drive member; a second belt having a length that is not a continuous loop and has opposite driven and drive ends, the second belt driven end being secured to the driven member and the second belt drive end being secured to the drive member; and a motive source operatively connected to the drive member to move the drive member about the drive member axis and thereby move the driven member about the driven member axis and move the signal light about the signal light axis.
