Abstract
A self-contained emergency signal has a base unit which contains a battery and an optional radio transmitter and a plurality of telescoping box-like stages which nest into the base member to convert it into a small container for storage and transport. Each of the boxes and the light mounting panels are cut in a special way to permit nesting of the boxes within the base container. When deployed for use the unit is extended into a vertical (or horizontal) array of sequentially illuminated letters which spell out the word 'HELP' or a similar word or different color panels, there being a control to sequentially flash strobe lights positioned behind each letter.
