Tools? Wire? Etc? 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. -Kent ________________________________ Message 2 _____________________________________ Time: 09:40:57 AM PST US Subject: AeroElectric-List: Instrument lights From: Peter Pengilly 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 ________________________________ Message 3 _____________________________________ Time: 10:32:51 AM PST US From: Bill Putney Subject: Re: AeroElectric-List: Instrument lights Peter, That would be a #330 lamp (probably CM330 is a specific manufacturer).

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.
