Abstract
A light bar is provided for mounting to a roof of an emergency vehicle such that the signalling devices comprising the light bar are distributed across the roof to form a non-linear pattern. A dome assembly covers the signalling devices and also forms a non-linear pattern traversing the roof. The light bar provides for enhanced visibility at angles approaching 90.degree. to the heading of the vehicle. Moreover, the non-linear pattern of the signalling devices allows the light bar to provide a signalling pattern whose warning effect can be alternatively directionalized into different distinct zones about the vehicle. In a preferred embodiment, each of the signalling devices is contained in a module comprising a base and a dome such that enhanced transmittance of light is provided at angles approaching 90.degree. from the heading of the vehicle.
