AC 0-20A Analog Panel Meter for use with house hold 120V / AC

Hi, for my craft projects of making 120V, AC lamps, for decoration purposes I would like to add round amp and or voltage meters in the lamp base that work when you adjust the dimmer switch on the lamp. Can I use standard round analog style AC 0-20Amp gauges directly in the circuit after the dimmer and before the lamp or would I need some type of voltage regulator? I would like to find old style round panel meters if anyone could provide some links. Thanks!
 
Welcome to EP!
You would have to find gauges rated for mains voltage and find a way of mounting and connecting to them without compromising insulation from mains voltage and hence safety.
