| May 15 at 14:13 | comment | added | Noel Whitemore | Thank you for everyone's suggestions. I think the lenses is the most important factor as far as the effect I'm trying to achieve is concerned, because the modern pilot/indicator lights look a little too modern and the way the light drops-off is an important part of that effect. The closest I've found to what I want, as a new component, is this raised indicator light. I have a sample circuit for the random blinking from an old electronics magazine but will look into using PWM to create a simulated light effect. | |

| May 15 at 0:05 | comment | added | periblepsis | @NoelWhitemore They were, then, incandescent. But they do need to be replaced from time to time and take a fair bit of power to be visible (emitting a lot in infrared and as heat.) No LED can really quite exactly replace an incandescent for the exact same effect either by eye or when recording, using a camera. You can still buy flashlight bulbs, today. Which, if you find the right holders and bezels, are equivalent. But LEDs may be the modern approach, accepting the differences in visual effect. | |

| May 14 at 23:34 | comment | added | Noel Whitemore | Thank you. I did wonder whether they might have used neon bulbs instead of incandescent, but the voltages would presumably be a lot higher for those and that would rule out the portable projects that I remember. | |
