Perhaps the problem was there were two types. The snag with one type is that
too long in the dark and the lite faded, the others were a bit thicker and
contained a radioactive gas, like in the original trimfone beta lites. These
were considered to be not safe, though in reality they were of course as it
was the phosphor that was glowing from the beta particles, and the
particles never made it through the glass.
In the case of neon ones, These are after my time of being able to see,
but it depends on how the illumination occurs. Most neon's end up going
black inside the glass, from the reaction with the ions I think, so if they
do not have replaceable lamps they end up dimming over time.
Who remembers the Decimo Jumbo digital alarm clock?
each segment in the display was in fact a miniature neon light wired into
a pcb and pushed into a hole behind frosted plastic, looked great when new,
but as the neon's aged all the segments were of different brightness's. I
spent hours replacing neon's on that thing trying to match up the
brightness's, all for it all to go out of whck a few months later. Nowadays
of cours one would use bright leds instead, but this was a long time ago.

About 50 years ago electroluminescent plates were introduced.
These sat behind a regular wall switch plate. Sometimes longer scews were
needed to pass through both plates and into the plaster-depth box.
Great. In a darkened room you cold see a blue glow (amost) around the
complete switch plate.
They only lasted a short time.
Now I am searching for something similar. MK appear to make a neon
equivalent but does it work and does it last?
Are there any successful alternatives?
