1 Claim.
(C1. 240—10.68)
My present invention, in its broad vaspect, has
to do with improvements in signal lights of the
type especially adapted for use with marine life
Saving equipment, and to that end it is construct
ed to be securely but removably attached to the
person carrying the light in a manner which will
permit the light to be elevated on occasion or
waved or the like to be visible at a distance, and
Brie?y stated, some of the objects and advan
tages of my invention are as follows; ?rst, to
provide a signal light for life preservers, life
saving suits, and the like vwhich is very light in
weight, and which is substantially water, mois

construction; second, to provide dual means of
attachment to a life preserver, life saving suit

furthermore it is designed to be waterproof and
fire proof, .to be easily and quickly operated, ‘and 10 around ‘without likelihood of becoming lost or dis
