Ozone indicator light

[Debo]

I recently bought a 2010 marquis mirage (thanks to all the helpful advice I got here . So anyway, I'm trying to figure out if the ozone is working. Does anyone know if the indicator light (if it's indeed on) would be visible in broad daylight?

For many models of ozonators the light will only tell you if it is getting power, not if it is producing ozone

From what I understand, the marquis' ozone is an all or nothing. Light on means it works no light means buy a new one :-/
