ABSTRACT:
An adjustable lighted walking aid adapted to be used in low light or dark areas is disclosed and may include a cane having a front light for illuminating obstacles being encountered in front of the user and a back light for simultaneously illuminating the area proximate the feet of the user so that the user may see and thus help avoid upcoming obstacles in front, as well as observe the area at his or her feet while walking. The cane may be used in its generally vertical manner during use to assist properly the stability of the user, and is adjustable in its length to accommodate a variety of users.
