Day/night cycle activated script doesn't work?

while wait(1)do
	if game.Lighting.ClockTime >= 20 and game.Lighting.ClockTime <= 7 then
		script.Parent.SpotLight.Enabled = true
		print("light on")
	else
		script.Parent.SpotLight.Enabled = false
		print("light off")
	end
end

I've tested it on local scripts and tried different variations of it. I get the prints but the light doesn't work. Yes, the script is committed.
