Code does not notice light is turned off?

Have I done something wrong? My goal here is when a light is turned off for more than between 30 and 50 seconds, a global variable will be set to true causing multiple other events to fire. I'm not having problems with the global variable, it's more that when I turn off the light, nothing happens. I put the print function in there to see if it's noticing that the light is turned off, but I never get the printed message in the output.

local blackFigureEvent = false
local Rand = Random.new()
while true do 
	wait(0.1)
	if workspace.HouseParts.BedLight1.LightPart.PointLight.Enabled == false then
		wait(0.1)
		print("Light is off")
		wait(Rand:NextNumber(30, 50));
		_G.blackFigureEvent = true
		print("Event activated")
	end
end
