35Z5s, 35W4s, and 35Y4s, all have a pilot light tap on the filament, the pilot light has to be connected across this, usually in parallel with a 1 watt resistor. It might be popping because the pilot lamp is connected in parallel across the entire 35Z5 filament rather then just one end and the tap.
