Yes, that replacement will work fine. So will almost any neon lamp
that physically fits. Your cost, after shipping, will be a little
more than the cost of a new checker plug...

These lamps can fail because of slow gas leakage, so if the other two
seem dim, or flicker, it might be prudent to swap them out as well.

Someone in this group mentioned a while back that if you send a check or
cash and prepay your order to Digi-Key, you get free shipping no matter how
small your order. That helps out when you only need a few parts.

Thanks for your reply.
