Claim Text:
1. A coupling for a powered search light comprising: a power body including a power device that provides electrical power or access to electrical power and having a corresponding longitudinal axis; a lighting head coupled to the power body, the lighting head including lighting device which provides light when electrically powered and having a corresponding longitudinal axis; where the power body has an end coupled to or included as part of the power body; where the lighting head has a receiving coupling coupled to or included as part of the lighting head; a compression O-ring seal provided in either receiving coupling of the lighting head or end of the power body to seal the power body and lighting head together from the ambient environment when the body and head are coupled with each other, a plurality of tabs defined on the end of the power body and extending radially therefrom; a corresponding plurality of flanges defined in the receiving coupling of the lighting head and extending radially inward therefrom, the power end arranged and configured to engage the receiving coupling by capture of the plurality of tabs between the corresponding plurality of flanges and lighting head, when the lighting head and power body are rotated relatively to one another, the plurality of flanges and lighting head each providing rigid opposed surfaces to each other, each of the tabs being confined between the rigid surface of a corresponding one of the flanges and the opposing rigid surface of the lighting head to provide a positive capture of the tabs therebetween, the capture of the tabs by the flanges longitudinally compressing the compression O-ring seal between the lighting head and er end so that the lighting head and power end are temporarily securely pressed to ether at the same time as the positive capture of the tabs securely couple the power end to the lighting head together; and a lock for selectively locking the plurality of tabs with respect to the plurality of flanges to prevent relative rotation of the lighting head with respect to the power end.
