Abstract
This disclosure pertains to a walking cane, for use by the blind, having a portion of the shank thereof adapted with a solar cell. The current produced by the cell recharges a battery stored within the hollow interior portions of the cane. A lamp is selectively energized by operating a control switch. The lamp provides illumination, warning others of the disabled condition of the user. A buzzer or other alerting device is selectively included in the electrical circuit which enables the user to test the successful illumination of the lamp.
