Flexible flashlight with LED light source

A flashlight comprising, in combination:

• a light source element;
• a elongate first flexible lead wire;
• an elongate second flexible lead wire, said first and second lead wires connected to the light source element in series;
• a separate battery housing having a lead wire end and a manual button operating end, said housing including a battery tube for receipt of at least one battery, said housing further including a lead wire fitting at the lead wire end for receipt of the first and second lead wires and for maintaining the first lead wire electrically connected to a battery in the housing, said housing further including a conductive series path to the second end, said lead wire fitting also electrically connecting the second lead wire in series to a battery pole of a battery in the housing;
• a button control mechanism for the flashlight mounted at the second end of the housing, said button control mechanism including a first series circuit connection between the series path and the button control mechanism, said button control mechanism comprising a conductive rod member with a projecting conductive knob for electrical contact with a battery in the housing to complete a series circuit through the battery, an insulator fitted on the rod member and a spring fitted over the insulator for biasing the insulator against a battery in the housing and away from the conductive knob, said conductive knob being longitudinally adjustable to engage the knob against a battery pole in the housing to close the series circuit and energize the light source element.
