Instrument lamp post

Instrument lamp post for dashboard.
If used in airplanes, of course experimental any use is on own risk.

You need a 5mm LED, a proper resistor for the voltage.
You can use a LED dimmer circuit if you wish.
I have used 4000mcd 20° led, a 1800mcd 30° would be just as good
Unshielded wire 22GA Tefzel, MIL-W-22759/16
A screw, MS35214-27, 6-32 thread, 1/2 inch long or whatever you need to mount it through your dashboard.
An electric wire eyelet to connect the ground cable to the screw body.

The screw is bored through down the middle with a 1,5mm drill.
It's not easy, but possible in a drill-press. First fix a piece of wood drill a 3,5mm hole into that.
You might need to use a router bit to center the hole in the wood, otherwise the drill can bend and drill a hole off-center.
Place the screw in the hole, keep it from rotating with pliers.
Drill a 1,5mm hole through the screw.
Use a sharp drill, drilling fluid, clean chips often.

Sand the head of the screw, put som soldering tin on it.
