Abstract
An illuminated, multi-function cane for use by low-vision individuals is described and claimed. The device's various pulsating lights enable low-vision people to travel at night with assured confidence that they will be seen by drivers and cyclists from a safe distance exceeding one mile on a dark street! While at a high traffic lit city intersection the Lumi cane is very noticeable with its strobing rainbow lights 200 yards away, even with competition from other bright artificial lights. Even in dense fog Lumi's LED lights are visible at 40 to 75 yards distance.
