Anyone know how to make or where to buy hidden till needed annunciator
lights?

My car has a row on the bottom of panel that is black and uniform, until
something is illuminated. Upon turning on ignition switch, all illuminate
as a test.

Better yet if one were to reverse label could it be installed as a heads
up display?

Thx.

This is fairly simple with a black background. You can simply flush
mount your lights in the panel, then put a mylar in front of them with
the lettering clear on black. Without back-lighting on, the letters
disappear, looking black also. Turn on the lamp, and bingo.

The black-out feature works best with a satin textured mylar.

A simple way to do this and avoid custom work is with a laser printer
and some overhead transparency stock. Make up your labels with
Publisher or some similar tool. Then print them. The quality of the
laser is important to getting a uniform coverage. Also, you may have to
scale the spacing up/down a little - there can be a couple of percent of
size variation when printed.

Finish off the system with a piece of smoked mylar or Lucite panel.
This will give you a finished look. The surface will be hard. The smoky
appearance will help mask any minor imperfections in the printing
process, yet will still let enough light through.

We used to use this kind of process in prototyping electronic units.
