Abstract: A car light having a variety of practical applications, for example, as a map light with its detachable plug being retained and as an illuminating or warning light for use outside of a car with the plug being detached from the body of the car light. The plug is sized to plug in the cigarette lighter socket of the car and to be retained in its receptacle when a cord is rewound on a reel within a cord chamber between a reflecting mirror and an outer casing by turning either of the mirror of the casing relative to the other.
