Abstract
An automotive daytime running lamp assembly includes an incandescent light source received within a reflector member. The reflector member is formed as a surface of revolution about a longitudinal axis and has an enlarged, first end, and a narrowed, second end with an opening that receives at least a portion of a light source therethrough along the longitudinal axis. A sleeve is received over a portion of the light source and at least partially extends through the reflector member opening. A cap received over the second end of the reflector member about the opening is fixedly secured to a disk, preferably by fusing or welding the components together. Likewise, the disk and metal sleeve are fixedly secured or fused/welded together so that the light source is fixed relative to the reflector member. A mounting member is provided for secure optical positioning of the assembly in a fixture of the associated automotive vehicle.
