I also found this: http://www.pdp8.net/tu56/tu56.shtml
in which Dave G. describes a successful use of the CM2182 (14V, 
80ma) bulb in this application.  There don't seem to be many 
low current bulb choices -- the CM2174 perhaps, but it's only 
about 1/3 as bright, and only about 1/4 as long-lasting.
