ABSTRACT:
A lightweight, compact lighting device, which may be detachably, rotatably attached to an earpiece of a pilot's earphone headset or to a military pilot's helmet, is primarily designed for use by pilots in the event of a blackout in the cockpit of an aircraft. The search and survival light is convenient to switch off and on by simply rotating a switch activator near the front of the device. The lighting device may be constructed separately for attachment to an earphone or it may be manufactured as an integral portion of a headphone earpiece. In another embodiment, a bracket is included for holding a compass and the device includes a fibre optic cable to light to the compass.
