Too Bright Invisible Lightsource at Night in Helicopters/Aircraft Cockpit

[tyrodes]

The rogue spot light happens in planes also:

C172 (Ski) interior spot light

Does anyone know how to turn off the interior light as seen in the picture, Cessna 172 Ski? I’ve searched the whole aircraft and can’t see where it’s coming from! It’s not flashlight as I can switch that on and off. [90b48877-a0e2-427d-86e1-a00ef5e40936]
