Light turning off at 18 clock time doesnt work?

I wanted to make light that turns off when clock time is > 18 and turns on when clock time is > 6 but for some reason it doesnt work and i dont know why

local plight = script.Parent --point light
local light = game.Lighting -- lighting

light.Changed:Connect(function()	
	if light.ClockTime >= 18 then
		plight.Enabled = false
		print(light.ClockTime)
	end
	if light.ClockTime >= 6 then
		print(light.ClockTime)
		plight.Enabled = true
	end
end)

It's because your script is checking if light.ClockTime >= 6 after checking if light.ClockTime >= 18, meaning even though plight is disabled for a millisecond, it is enabled the next milisecond, since if it is greater than 18 then it is also greater than 6. The fix is simple - rather than putting end and starting a new if-statement, just use elseif as replacement.
