In this write up you can see he addresses the problem of the neon bulbs not being able to light in the dark with blue leds. I wonder if you could use ir leds and keep it invisible On Tue, Jul 22, 2025, 5:13 PM 'Grahame Marsh' via neonixie-l < [email protected]> wrote: > Hi Jarod > > I skipped neon bulbs and and used trigger tubes.
