A light bar for mounting on an emergency vehicle to provide warning light signals, comprising at least two vertically spaced lighting layers, each layer having at least one light source, the light sources on each layer cooperating to provide a transient high intensity warning light signal 360.degree. around the light bar. The light bar may include oscillating light sources. A casing encloses the light sources, and a divider separates the light sources of at least two of the layers and divides the casing into at least two vertically spaced layers. The divider includes means for permitting air convection between the layers while blocking direct light transmission from the light sources on one layer to the other layer. The casing comprises upper and lower shell members which interfit to horizontally compress a gasket to seal the casing without screws or other fasteners penetrating the shells. The light bar preferably includes a hollow tube extending substantially the length of the light bar, for mounting the light sources. The tube may be formed by upper and lower channel shaped members. A plurality of stationary lights can be incorporated into one of the layers of the light bar, and electronically controlled to provide traffic directing signals.

Light bar

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.
