"Rechargeable red flashlights...isn't it funny how a little
thing like that can bring back so much...I think I lived
with one in my mouth every night, all night for a
year...kept our hands free and allowed us to work in the
dark." [PW]
We used little Sonys, with two bulbs, one red, the other white.
Plugged into a 110VAC wall socket and charged back up overnight.
Perfect shape to fit in the mouth (except when wearing an O2 mask) and
you could clamp down on them with your teeth and they would never fall
out.
"Don't remember if flashlight was Sony or not, it did have
one red and one white bulb. Still have mine somewhere. I'll
have to dig some and find it. Charged up all day and used
all night." {PW]
Turns out that the old memory cells were deader than the batteries on
a 25-year-old flashlight.
"The little flashlights were Sanyo. I have one in the
basement, alas it is dead. I have the box it came in down
there also. Sanyo Cadnia Lite, Model number NL5100, Twin
bulb (Red/White) 117V Recharging." [DZ]
