Re: [at-l] The Flashlight caper...



Earl,  why pussyfoot around like this? 
How about sodering a short length of wire to each end of a battery
(whatever size suits your fancy) and sodering another pair of short wires
to a bulb.  Then connect the corresponding ends of the battery wires with
the bulb wires (twist bare ends saves the weight of crimped connectors). 
Perhaps some sort of metal solder adhesive could be used instead of real
soder.  Soder up a few extra batteries as replacements via mail drops,
etc.  This way you avoid the weight of any flashlight case, switches,
reflectors, or lenses.
