Abstract: An emergency vehicle signal light adapted to be mounted on an emergency vehicle. A light source emits visible light for illuminating a reflector. A light pipe having one end associated with the light source has its second end associated with a diverter for diverting substantially all light transmitted by the light pipe toward the reflector. The reflector is adapted to reflect the diverted light transmitted by the light pipe for observance by an observer remote from the emergency vehicle. A motion driver may be provided for rotating or oscillating the reflector about the diverter. As a result, an observer is adapted to observe discrete flashes of light resulting from flashing, rotation or oscillation, each flash corresponding to diverted reflected light forming a beam. For oscillating or rotating modules, the beam traverses across the position of the observer in response to the rotational or oscillatory motion. Alternatively, such modules may be used as part of a light bar.

Abstract: 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.

Abstract: A base adapted to be mounted on a vehicle supports a light source for generating a rotating light beam. A dome-shaped lens is positioned on the base over the light source to form an enclosure for the light source. A coating may be located on the top of the lens to prevent light passing therethrough and into the passenger compartment. Multiple flashes are created by a reflector positioned adjacent the rear portion of the lens to reflect the rotating beam as a plurality of discrete flashes within a sector relative to the base. A filter generally having a contour of the front portion of the lens may be mounted thereon. The multiple flashes may be of different colors depending on the range of wavelength of light transmitted by the lens and filter and reflected by the reflector. A person viewing the light sees at least four discrete flashes of light which may be of varying colors.

Abstract: A signal light assembly for vehicles requiring positive visual identification for either emergency service or traffic control usage, in which an identification beacon is provided with rotating lamp carrying pod means having the lamps positioned to produce an effective pattern of light flashes and dark periods from remote observation position to the front, to the rear, and to the sides of the vehicle, the result of which is effective to draw attention to the vehicle.
