Abstract
A spotlight assembly conformed for electrical excitation through the cigarette lighter of an automobile comprises a hollow housing formed by mating a front and a rear housing halves, each half including an upper portion for receiving a bulb and a lower portion forming a handle. The bulb, preferably of the sealed beam type, is retained against outward progression by an inwardly directed lip in the upper front portion and is pressed against this lip by an annular ring in the rear upper portion, the ring being guided by axially aligned posts for compression against the bulb by helical springs on each post.
