Abstract

A vehicle lamp assembly comprises a dished reflector in which is disposed a filament. The filament is disposed at an angle, preferably 30 DEG to 45 DEG , to a horizontal plane in which a principal axis of the reflector lies. The filament may lie with its axis perpendicularly disposed with respect to the principal axis. The lamp assembly may further include a parabolic mirror or lens spaced from the reflector and a mask between the reflector and the mirror or lens.
