Re: [electronics101] wife reminded me of the 6/12V test light...

Mine uses a bulb sort of like an AGC fuse, or European dome light, with the terminals on each end.

I suspect it will be less expensive to buy a new one or rig your own using a small 12V bulb.

I just ordered a "probe" with a built in voltmeter, it would be useless for placing in series to measure parasitic load but nice to verify the actual voltage at a test point. With modern cars the difference between 10 and 12V might be enough to be a problme

The Electronic Goldmine has a lamp 6/12V tester

I ordered several as 'gag' (but practical) gifts for friends and we have one in each car.

I have one of these testers but the bulb is gone. I searched w/o success for a replacement 'bulb?' Anyone know where I might buy a replacement bulb?

[sherline] Laser/Non-Contact Dial test indicator tool?

Any suggestions for an affordable Laser/Non-Contact Dial test indicator tool? I have tried a lot of searches and found nothing. There are a number of laser measuring tools for large distances (100 feet or more) but they only have accuracy to tenths or perhaps hundredths of an inch but not to Thousandths or ten-thousandths that would be desirable for machinist work. There are paint thickness gauges for under $30 that claim to have such resolution so it can be done cheaply. I have done a lot of searches for a laser or contactless measuring tool to replace my mechanical Dial Test Indicator tool but have found nothing. Suggestions wanted!
