KL4 Pila resistor ?s

[Bright Scouter]

I am hoping to run a kl4 that I have coming with a Pila 168s batt I have coming. I want to put it in a body with a McE2s switch. Any recommendations for a resistor value to order? I would like the low side to be pretty low.

I'd say either 15 or 22 ohms. It's tough to tell without trying it out.
