1. A wearable light device;
- including;
a mount adapted for being worn on the body;
a light system;
including;
a circuit board;
a plurality of visible light sources attached to said circuit board for emitting light generally parallel with the wearer'"'"'s direction of gaze; and
a light sensor attached to said circuit board for sensing light approaching said sensor;
a power source for energizing said light sources, said light sensor, including;
a battery;
a housing for said battery; and
a cable connecting said battery and said light system for transmitting electrical energy to said light system; and
a control circuit for decreasing the intensity of light emitted from said light sources in proportion to the intensity of light striking said sensor.

Abstract
Wearable light device for providing additional light for activities in low light includes a wearable mount (20) including a light system (30) and power source (40). Light system (30) includes one or more arrays of light sources such as light-emitting diodes (33). Photo sensor (34) detects ambient light or emitted light returned from a reflective surface and causes control circuit (45) to dim light emission.
