6v Indicator LEDs

I put a spiffy green 3v panel mount LED in my nixie clock recently that I like the look of. I noticed they make them in a 6v version as well, which I figure should work pretty well on the DC heated kits.

I personally have left on both my Mainline, and Eros 2. Between the tube shields and the chromed tops of the reg tubes it's been easy for me to forget (unlike the Crack variants with bright 6080s). Any concerns with wiring in one of these 6v LEDs to the 6.3VDC heater connections? What would be the ideal place to hook them up?

Less critical (I can usually see some glow on the 6CM7s), but I'd also like to set one up on the BeePre2...if possible. Looks like the 6.3v line on that is AC but seems to be a possible 6.5vdc tap elsewhere on the voltage checks.

Thanks as always!

I don't see any reason that these wouldn't work on AC as well.

Just be sure there's infinite resistance between both terminals on that LED and the metal housing.

Thanks PB, I'll double check that. Do you think that reg ol' unshielded wire would pick up additional noise to the audio signal and should I find some shielded twisted pair similar to the existing heater wiring? Would daisy chaining off the last 6.3v heated tube be best?

If you're putting this on a Mainline or an Eros, there isn't going to be a lot in the way of noise on the heater supply to radiate anywhere.
