Have you "aged" the INS-1's before use? Many neon indicators needs to be "aged" properly before use so the ones not working properly can be removed, you can read about aging neon indicators here: http://www.dos4ever.com/ring/ring.html , scroll down to "More on Neon Tubes" to read about aging, but read the rest too as it is interresting reading! /Martin
