Ziplights!
Zippo used to
produce these a few years ago. They made them for about 3 years
and then stopped. I
guess there wasn't a demand for these things. I love them. It helps
with my work. Having
a light source to shine through fiber is very handy.
After a few weeks of
use the batteries went dead. I searched the town high
and low for
replacement batteries. But Zippo had the market on these. So
I found a 12v
battery that fit, changed out the bulb with a LED, added a
resistor and I have
been using this for over a year now.
