Re: (erielack) Odd signal

["Gary R. Kazin" <gkazin_@_yahoo.com>]

Although it looks like the bulb is turned off, it is in reality connected
to a low voltage circuit.  It isn't enough to light the bulb, but it keeps
the filament warm and avoids the thermal shock of turning the bulb on and
off entirely.  This gets most of the savings in battery power and bulb
life.
