Abstract: A utility emergency light assembly for vehicles, machinery, or the like detachably mounted by a slide coupling to a mounting bracket attached to the vehicle or machine. The light assembly has a compact, space-saving profile and includes a housing having a lamp assembly mounted within a spool journaled in the housing for reeling and unreeling a power cord, enabling movement of the assembly to areas of the vehicle where light is needed. A cap substantially closes the housing and includes a lens located over the lamp assembly. The lamp assembly is sealed within the spool, while the remainder of the housing is open to allow water drainage and to prevent the accumulation of moisture and debris.
