Our bathroom light wasn't working. I finally got the cover off and inspected the bulb. It appears to be good, no discoloration and no broken filament. I am wondering if any current is getting to the bulb. My problem is that the bulb inserts into two extremely tiny holes. My meter's probes are too fat to fit into them. The bulb fits into a tiny ceramic piece with two wires coming out the back. The wires are covered with insulation, no bare wire exposed.How can I test to see if current is making it to the fitting?One more piece of info, this fixture would sometimes flicker before it stopped working.Del

Is there another bulb that's good somewhere that you can test with?

OF course it could not be that easy. All the other bulbs are larger.

Wrap small solid wire around your meter leads or use a sharp lead to lightly pierce the insulation.I'm assuming you read out the bulb?You're looking for voltage - not current.

Use two pieces of wire that are about the same diameter as the light bulbs pins to "probe" the socket. Touch your leads to these probes. And yes, you're looking for voltage.Check the light bulb for continuity if you haven't already.

OK, thanks to all. I just checked the bulb with my meter and no deflection at all, so the bulb is bad.

So simple, I am ashamed.

Again, thanks.

OK, not to rub salt into your wound but you did have the meter set on the ohms scale? :-)

I was going to ask the same question, but decided not to. I know that I have done it a few times when not thinking.
