By popular request, a look at the chunky panel indicators I used on the generator changeover switch video. These ones came from this eBay listing:-
https://www.ebay.co.uk/itm/371713535356
They have a wide range of indicators, but keep in mind they are probably aimed at the Chinese industrial market and may not comply with local standards.
These indicators will work on a wide voltage range but will be dimmer at lower voltage. If the internal capacitor is shorted out the indicators will work on 12V-24V DC if the existing internal resistor is 1200 ohm half watt as it is in this indicator.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

I dont know much about this stuff but i have a lot of old indicator lights….like the small ones you have there. Mine are glass though and some have bulbs in them. Is there any way i can test them with a 9 volt or an easy way to test them at home with normal batteries? If not what exactly do i need to test them out? They used to go to a bunch of HAM radio equipment. Thanks
For those interested these appear to be either an AD11-25 or AD11-40 since the link is dead and they are quite stylish
Common neons in my experience were the NE-2 (wiires) and NE-51 (bayonet base, similar to a #47 tungsten lamp). I never saw screw-in ones of the size you showed here. There were some bigger screw-in types, like the NE-45 ferinstance, I had a tape recorder (early 1960s vintage?) that used a couple of those for level indicators. But the last time I looked they were absurdly expensive…
No vice of knowledge?
If you do not bother to open the LED case itself then what is the point in guessing the possible four-diodes configuration on schematic. Sigh !
Could I run these LED's from USB power at 5v? Perhaps by changing the capacitor to a low voltage resistor?
That doesn't look like an X or Y rated safety capacitor. Are those safe to use with a standard high voltage capacitor as built???
what's that resistor disk called? seems handy and i could use it. where can i get one?
hey, got a question can you do a video on how to recover powertool batterycells that are undercharged and are no longer accepted by the charger, how to fix it or check if you need to buy a new battery?
Those large indicator lamps are perfect for a 1970's style lair – for the discerning criminal mastermind.
Wah, ha, ha, ha, ha, ha, ha!
thanks for taring these open. simple as i thought they'd be.
I am surprised you didn't comment that a discharge resistor would make a much safer device. I guess you can't ask too much from Chinese crap.
