HP power button neon
veedub565:
Hi, does anybody know a source of replacement neon's for the older HP illuminated power buttons (see picture)
I tried goggling thr HP part number but haven't come up with much.
And an image search just throws up lots of hits for miniature bulbs, which it's isn't it's definitely a neon (95v in this case)
DLJ:
I googled "T1 neon" and found this https://www.ebay.co.uk/itm/293178384132
No idea if this seller is any good, or even if this part would work for you.
It might just be the entrance to a very deep rabbit hole.
Happy hunting.

Ah perfect, thanks. I didn't even know it was called a T1 neon, or sub midget flange
schmitt trigger:
You may receive suggestions to replace the neon with an LED, by adding a diode and changing the limiting resistor.
Unless you absolutely cannot find a suitable replacement neon, I would not recommend it. I may be prejudiced, but I positively love the soft neon glow. And you would keep your vintage device, well, vintage.
factory:
They are usually an A1H neon, the one linked in reply #1 is too small.
