Asong AS-235 power feed??

[Highpower]

I've always wondered why I could barely see the "power light" on my table feed. Now I see it's because what I assumed was a bad LED, is actually a neon lamp under a plastic light tube/fiber optic.

Does anyone know what voltage/current that lamp runs at?
I would love to be able to replace mine with a LED that I can actually see when it's on.
