this item is an all-original concept, first introduced by f-three. night runner's beacon lights are usually attached to an arm-band or something that fits some other specific spot...this beacon uses thee strong neodymium magnets, holding the top panel to the bottom...allowing the end-user to place the lightweight, reflective piece anywhere on his person...replaceable battery and on/off switch at back of front panel....soft pile at back of back panel for comfortable contact with skin.
