Caution

The battery used in the light is very powerful. Be
sure that the switch is not touching anything when
the light is stored. If the lamp is turned on while in a
case or other container, the lamp can overheat and
damage the light or surrounding materials. Remove
the battery or unscrew the bezel far enough to
prevent the lamp from turning on when stored.
Do not use a 3 Volt Lamp Assembly in a 6 Volt
system. The lamp will burn out Immediately!!! To
identify a lamp assembly: the 3 volt lamp has a Red
label and is marked R30, the 6 volt has a Blue or
Green label and is marked R60 or P60.
If it is necessary to dispose of any batteries, do not
do so by fire, mutilation or by disassembly, as this
may cause toxic chemicals to be released.
