face and a rearward face intersected by a bore, the rearward face having a generally annular flat with a
series of depressions; a bulb providing a source of illumination positioned generally adjacent the reflector
housing forward face; a bulb housing providing an electrical connection for the bulb and for mounting the
bulb, the bulb housing having a first portion inserted within the housing bore and a second portion positioned
generally adjacent to the reflector housing rear face annular flat contacting the same; a generally annular
retainer having a first portion extending through the reflector housing bore and a second portion contacting
the rear face of the reflector housing within the depressions of the rear face, the retainer also having an
interlocking flange spaced from the second portion with biasing tabs for retaining the bulb housing within the
reflector housing bore and urging the bulb housing against the reflector housing rear face; a shield for
blocking a portion of the illumination generated by the bulb, the shield having a main body portion connected
with legs which are in turn connected with an annular ring, the annular ring contacting a forward face of the
reflector housing; and a connecting subarrangement connecting the first portion of the retainer with the shield
