Abstract
A reflector for rotatable signal lights includes a pair of coaxial parabolic reflecting surfaces which are interrupted and joined back-to-back with the juncture forming an aperture which defines a plane through the common focal point of the two reflecting surfaces. A lamp is positioned within this aperture so that its filament is intersected by and perpendicular to the plane formed by the aperture. The doubled-ended reflector and associated lamp is used in conjunction with any conventional type of rotating of oscillating drive.
