Abstract
A visual indicator includes a solar panel, a rechargeable battery operatively connected to the solar panel for charging the rechargeable battery with power from the solar panel, a light emitting diode (LED) operatively connected to the rechargeable battery to emit light, and a controller operatively connected to the rechargeable battery and the LED to control operating characteristics of the LED. A method of operating a visual sensor includes recharging a battery from a solar panel, emitting light with a light emitting diode (LED) from power provided by the battery, sensing ambient light conditions proximate to the visual sensor, varying an intensity of light emitted from the LED based on the sensed ambient light conditions.
