At least three vertically spaced lighting layers are provided, each layer having at least one emergency light source, the emergency light sources on each layer cooperating to provide a transient high intensity warning light signal 360.degree. around the light bar. At least four linear rows of emergency light sources as viewed from the top of the light bar are also provided, the rows being substantially parallel to the elongate axis, each row having at least two emergency light sources, at least one row located in each of the layers and at least one layer having at least two rows, the emergency light sources in each row cooperate to provide a transient high intensity warning signal 360.degree. around the light bar. Each end of the body has projecting extensions which have a recess for accommodating mounting hardware. A spot light or other device may be nested in the bar. The…
