Abstract

A vehicle lamp is provided with a projection lens having a lens profile with a rear major surface with a convex curvature and a front surface with a concave curvature. A rear height of the rear major surface is greater than a front height of the front surface. The lamp has a plurality of light sourcesand a reflector configured to reflect the light emitted from the plurality light of sources towards the projection lens. As the lens profile is swept along a curve length, at least one of the rear convex curvature or the front concave curvature varies. The light output from the front surface of the projection lens is generally uniform along the curve length.
