While true loop scrip not functioning as intended?

while true do
	wait(0.03)
	if script.Parent.on == true then
		script.Parent.G1.a.Transparency = 0
		script.Parent.G1.a.SurfaceLight.Enabled = true
		script.Parent.right.Transparency = 0
		wait(0.05)
		script.Parent.G1.a.Transparency = 1
		script.Parent.G1.a.SurfaceLight.Enabled = false
		script.Parent.right.Transparency = 1
		wait(0.05)
		script.Parent.G1.a.Transparency = 0
		script.Parent.G1.a.SurfaceLight.Enabled = true
		script.Parent.right.Transparency = 0
		wait(0.05)
		script.Parent.G1.a.Transparency = 1
		script.Parent.G1.a.SurfaceLight.Enabled = false
		script.Parent.right.Transparency = 1
		script.Parent.G2.b.Transparency = 0
		script.Parent.G2.b.SurfaceLight.Enabled = true
		script.Parent.left.Transparency = 0
		wait(0.05)
		script.Parent.G2.b.Transparency = 1
		script.Parent.G2.b.SurfaceLight.Enabled = false
		script.Parent.left.Transparency = 1
		wait(0.05)
		script.Parent.G2.b.Transparency = 0
		script.Parent.G2.b.SurfaceLight.Enabled = true
		script.Parent.left.Transparency = 0
		wait(0.05)
		script.Parent.G2.b.Transparency = 1
		script.Parent.G2.b.SurfaceLight.Enabled = false
		script.Parent.left.Transparency = 1	
	end
end

I have this script. I am trying to make it so if on is true the following will run. It is not working in game and not listening at all. It also won't return any errors.

Probably this: "script.Parent.on == true"

If you're checking if it exists, do: "script.Parent:FindFirstChild("on")" but if you're checking if a BoolValue's Value IS TRUE, do: "script.Parent.on.Value == true"

Silly mistake from me. :/

If you are defining a part(as in the on), == should work.

the if statement does not need to be there. classic should work

as in this

script.on == true

then at the end

script.on == true

Parent does need to be there
