A hand-held flashlight with gripping means is connected by a retractable tether to a spool housing. The flashlight is a self-contained unit with a light emitting diode (LED) light source, batteries and a contact switch. One end of the tether is connected to the base of the flashlight. The other end of the tether is wound round the spool in the housing. A coil spring is mounted between the housing and spool to bias the tether in a retracted position around the spool. The contact switch automatically turns on the flashlight when the flashlight is extended away from the housing and turns off the flashlight when the flashlight is retracted back to the housing. The contact switch can be a magnetic reed switch or a pushbutton switch. The gripping means allow the flashlight to be held securely by hand in any weather condition or environment.
