How would i make a light turn off if i have it on?

So when i turn on the light it lights up but when i want to turn it off i want to click it again How would i do this? Here is the code

local sp = script.Parent
sp.ClickDetector.MouseClick:connect(function()
	local l = Instance.new("PointLight", script.Parent.Parent.light)
	l.Brightness = 11
	l.Range = 11
	l.Shadows = true
end)

--I just want it to shutoff after i click it agian

I suggest not making one in a script, but putting it there already at script.Parent.Parent.light!

sp.ClickDetector.MouseClick:connect(function()
    	if script.Parent.Parent.light.PointLight.Enabled == false then
		script.Parent.Parent.light.PointLight.Enabled = true
	else if script.Parent.Parent.light.PointLight.Enabled == true then
		script.Parent.Parent.light.PointLight.Enabled = false
end)

So what I mean is put one in the part called light.

If helped then accept answer please!

I'm pretty sure CheeseDevie's will work, but this is a more efficient way of doing it (assuming it'll work with a property instead of value) --

sp.ClickDetector.MouseClick:connect(function()
	script.Parent.Parent.Light.PointLight.Enabled = not script.Parent.Parent.Light.PointLight.Enabled
end)

-- All it does it sets the point light's enabled value to the opposite of what it currently is.
