Abstract

An improved automotive lamp unit is provided having a shape to reduce the air resistance when the automotive vehicle moves. Specifically, the lens member of said automotive lamp construction is aligned in a non-vertical direction when bonded directly to the reflector member so that the lamp unit slips through the air with less resistance than occurs with the conventionally designed unit. The preferred embodiments illustrate various shapes of the lens member to include both rectangular-shaped and circular-shaped lens members having various prism element constructions.
