Abstract
A signal light comprising a base, a frame pivotally mounted on the base for pivoting about a first axis, and a bracket pivotally mounted in the frame for pivoting about a second axis, generally perpendicular to the first axis. A light source is mounted on the bracket so that it pivots with the frame and bracket about the first and second axes. The signal light includes apparatus for pivoting the light source about the first and second axes. This apparatus comprises a disc, having grooves forming first and second cam surfaces. The grooves are preferably located in opposite faces of the disc. A first cam follower follows the first cam surfaces and causes the frame to pivot. A second cam follower follows the second cam surface and causes the bracket to pivot.
