Wiring up switch w/pilot light...

When wiring up a switch that requires another wire back from the load to attach to the switch to power the pilot-light (illuminated when ON).
Do I have to use #14 wire ? Or can I use something smaller like #20 bell wire as long as the jacket is rated at 600v ?

Any help is appreciated.

I checked w/local supply houses and they wanted $150 for 250' of 14/4 wire.
Found it on HomeDepot site for $83 (free ship to store).
Inside the the box the 2nd switch controls a light literally 20" from the switch, I could easily get a neutral from there. Leaning back toward just running 14/3 back to the light 70' away. Seems kind of ridiculous to run a neutral back 70' to run a neon lamp ? I will setup the switch on the workbench and measure the amperage that the pilot lamp draws.
