I just installed a lighted two way rocker switch, and it works correcly as far as the indicator light goes (on when switch is open, off when closed). Since I don't have a fixture hooked up yet, I used a simple voltage tester (lights up when it detects 120V) to make sure power was going to the load side when the switch was closed. The tester did light up when the switch was closed, but the weird thing is it was still dimly lit when the switch was open. Is this normal behavior for a lighted switch? I changed the switch out to a standard non-lighted two way and everything checked out as you would expect. Any help? Thanks!

Those test lights use small neon bulbs that take very, very little current. And they can often give faint glows due to leakage currents.
I can take one hold one lead in my hand and connect the other to the hot wire and get that glow.
Typically the switch uses a similar light bulb and it will allow enough current that to flow that the test light will glow slightly.
