Abstract
An emergency vehicle light fixture includes, among other things, an elongated body having a reflective surface formed by a series of alternating linear and revolved parabolic segments. The series of alternating linear and revolved parabolic segments are coextensive along the height of the reflective surface and have an optical axis. Each of the alternating linear and revolved parabolic segments has a focal point that lies along a common axis that is orthogonal to the optical axis.
