Abstract
An emergency exit sign includes a support assembly which permits rotation of lighting heads, about an upright axis, through an angle greater than 180°. A freely rotatable joint element is used to maintain the lighting heads, in cooperation with mating facets, in various positions without the need for mechanical fasteners. The lighting heads are also attached to a snap connector which, enables the lighting head to be shifted about an arcuate axis, as well as rotated about a still further axis which is substantially perpendicular to the upright axis.
