In the larger commercial Allen & Heath and Grass Valley mixers, there are loads of square buttons that have little lights inside them. I'm wondering where to get them.
In the past, someone swapped out the red, blue and green lights for yellow ones, probably because they had them in surplus. Now I want to put them back the way they were.
Please let me know if you can point me in the right direction to get them replaced.

LED, one leg 22k to 150 k, and one 1N4007 on the other.
Should work.
You also get those ready, but I have no sources.
Those values are for 220 V mains....change as per supply.
Feed green ones 1.5 volts, 10mA; red about 2V/10mA, and blue about 3 to 4 volts DC, 20mA.
You will have to do some changes, as most new LEDs are super bright.
