I'm on my 3rd Hubbell 1203PL 3way pilot light toggle.
(light on - load on)
Honest to God the pilot light only seems to last 8 months. That's terrible. I'm going back to put in a Leviton switch this time and see what happens. I put the meter on there and checked everything in there and it's wired correctly. Nothing funky going on.
I have a couple of those ( of the single pole leviton variety) on a furnace and power vent water heater circuit and have noticed the indicators have become really dim, but still visible. Mind you they have been on almost 24/7 for the past 8-10 years. Perhaps the hubbell have had a defective run of switches or the little neon indicators?

Use a LED, run it at 3 mA and problem is sorted for life. I use a 66 k.Ohms 2 watt resistor for 230 Volts ( 2 x 33 K ohms 1 watt in series ) Then a 1 N914 diode antiparrallel with the LED. For anyone knowing basic soldering and tidy working it is a easy to fit in any switch with perfect results. also no heating in the resistors.
For 110 Volts design the circuit to run at about 3 mA which is ample for a high efficiency led. a single 33 or 39 k Ohm 2 watt resistor will suffice.
I have found neons with the incorrect series resistors which means excessive current and a short lifespan.
The product of rotation, excitation and flux produces electricty.
