Shrink-wrap! A fistfull of 1/4 down to 3/32 and all the colors of the rainbow.
Clear version too, if you want to make wire labels and shrink-wrap them. The
ordinary stuff works OK. There are some special tough irradiated versions
that are desirable in some areas.

Dear All,
After a minor panel re-build I'm trying to provide lighting for a couple of
round instruments. I have found a pair of eyebrow lights in my spares box,
but they have 24v bulbs. Does anyone know of a 12v alternative to a CM327
instrument bulb?
Thanks, Peter

Peter,
That would be a #330 lamp (probably CM330 is a specific manufacturer).

Peter,
Mouser Electronics (mouser.com) lists the CM327 as a T-1 3/4 midget
flange base incandescent bulb. The 14 volt equivalent is either the
CM330 ($0.55@) or the long life (15,000 hours) CM382 ($0.80@).

I've used several similar products and they seemed to
be of good value. You will want to limit the 'travel'
on the control potentiometer such that output never
exceeds 7v on a 14v system. The stock controller will
allow output all the way up to what ever the bus
voltage is.
You can do this with a mechanical stop on a pointer
knob . . . or perhaps add a resistor in series with
the potentiometer body such that full travel on
the pot represents only 1/2 of the original electrical
travel.
