Fitting neon colon separators. IN-14 All in one Arduino clock

Hi all This might be another dumb question unworthy of an answer but here goes.
I have 4 x neon separator lamps that I would like to make use of.
I know I have to connect P1 “170V” to “COM” and use 120k resistors in R38 and R39 but what "wattage" should the resistors be?

A quick note. Depending on the type of neon separators you are using, you may want/need to increase the values of the resistors to 220k or even 330k to avoid dimming of the digits when they reach full brightness.

On the two that I've built with IN-1's as separators, I found 220k to be much better.

Thanks for your replys gent's I was going to use the one in this image

That looks like a standard IN-1. I think you''l like the results of using 220k resistors instead of 120k's. Try them both and use whatever works best.
