## Abstract

A walking cane is provided having an elongated length, a handle grip, a forward-directed illumination source, and an ambient light sensor. The device provides a cane-user with forward illumination during twilight and dark periods, whereby the ambient light sensor operably energizes the light source when in an appropriate operational mode. A secondary mode allows the user to manually operate or deactivate the light source by hand controls, wherein each option is selectable from a three-way switch at the base of the handle grip. The length of the cane may be adjustable and its structure may take on an ergonomic shape, while the lower distal end is capped with a cane ferrule.

## Claims

### Claim 1

An illuminated walking assistant, comprising:
an elongated shaft member having a handle end and a distal end;
said handle end comprising a handle grip, a removable power supply, and an electrical switch;
a light source along said shaft member;
an ambient light sensor along said shaft member;
said power supply, electrical switch, light source, and ambient light sensor in electrical connectivity with one another;
said ambient light sensor adapted to energize said light source when ambient light dims below a given threshold;
said switch further comprising a three-way switch adapted to operably allow for continuous light operation, deactivating said light source, or finally allowing said ambient light sensor to operably determine when to energize said light source.

### Claim 2 (depends on 1)

The device of claim 1, wherein said light source further comprises a light emitting diode and associated electrical circuitry.

### Claim 3 (depends on 1)

The device of claim 1, wherein said elongated shaft is telescopic and adapted to change lengths and secure in a static working state.

### Claim 4 (depends on 1)

The device of claim 1, wherein said elongated shaft member distal end further comprises a cane ferrule.
