<p>A spotlight assembly (10) has inner and outer hemispherically shaped mounting members (20, 21) fixed to the roof (R) of a vehicle (A). Inner and outer movable frames (12, 14) are mounted on the fixed mounting members (20, 21) for relative rotative and tilting movements upon actuation of a handle (78). A lamp unit (16) is mounted on outer movable frame (14) about horizontal pivots (90, 91) from linkages (106, 50, 51). The tilting movement of handle (78) results in a tilting movement of lamp unit (16) around three times the angular movement of handle (78) to permit lamp unit (16) to be easily folded to a protected retracted position as shown in figure 3. The spotlight assembly (10) is easily installed on the roof (A) by first securing the inner and outer fixed hemispherically shaped mounting members (20, 21) to the roof (R), then mounting an upper movable subassembly on the outer mounting member (20) with an operating shaft (43) extending through the opening in the roof, and next mounting the lower movable subassembly on the inner mounting member (21) with the operating shaft (43) being received in an interfitting telescoping position for actuation by a handle (78).</p> |
