Value and transparency changes for signal?

I'm creating a signal system. I've added 2 Boolvalues into the signal. One called "red" and another one "green". I want a red light to appear(red cylinder) when the Boolvalue "red" is true. And then when the "green" is true I want a green light to appear and make the red light disappear. This is the script I have in the signal I want to change

red = script.Parent.red
green = script.Parent.green

if red.Value == true then
	script.Parent.Red.Transparency = 0
	script.Parent.Green.Transparency = 1
	script.Parent.Yellow3.Transparency = 1
	script.Parent.Yellow2.Transparency = 1
	script.Parent.Yellow1.Transparency = 1
	green.Value = false
else
	red.Value = false
	script.Parent.Red.Transparency = 1
	script.Parent.Green.Transparency = 0
	script.Parent.Yellow3.Transparency = 1
	script.Parent.Yellow2.Transparency = 1
	script.Parent.Yellow1.Transparency = 1
end

The way I tried it out is with a junction with the script

Check = script.Parent.Check

script.Parent.Changer.ClickDetector.MouseClick:Connect(function()
	if Check.Value == true then
		script.Parent.Changer.Transparency = 0.5
		script.Parent.Left1.Track110.track1.CanCollide = true
		script.Parent.Left1.Track110.track2.CanCollide = true
		script.Parent.Left2.Track110.Track1.CanCollide = true
		script.Parent.Left2.Track110.Track2.CanCollide = true
		script.Parent.Left3.Track110.track1.CanCollide = true
		script.Parent.Left3.Track110.track2.CanCollide = true
		script.Parent.Left4.Track110.track1.CanCollide = true
		script.Parent.Left4.Track110.track2.CanCollide = true
		script.Parent.Right1.Track110.track1.CanCollide = false
		script.Parent.Right1.Track110.track2.CanCollide = false
		game.Workspace.PUsignalspor1taulovmodKolding.Model.PUTEST.red.Value = false
		game.Workspace.PUsignalspor1taulovmodKolding.Model.PUTEST.green.Value = true
			
		Check.Value = false
	else
		script.Parent.Changer.Transparency = 0
		script.Parent.Left1.Track110.track1.CanCollide = false
		script.Parent.Left1.Track110.track2.CanCollide = false
		script.Parent.Left2.Track110.Track1.CanCollide = false
		script.Parent.Left2.Track110.Track2.CanCollide = false
		script.Parent.Left3.Track110.track1.CanCollide = false
		script.Parent.Left3.Track110.track2.CanCollide = false
		script.Parent.Left4.Track110.track1.CanCollide = false
		script.Parent.Left4.Track110.track2.CanCollide = false
		script.Parent.Right1.Track110.track1.CanCollide = true
		script.Parent.Right1.Track110.track2.CanCollide = true
		game.Workspace.PUsignalspor1taulovmodKolding.Model.PUTEST.red.Value = true
		game.Workspace.PUsignalspor1taulovmodKolding.Model.PUTEST.green.Value = false
		Check.Value = true
	end
end)

The check.value is to check if the junction is going straight(right) or left

	game.Workspace.PUsignalspor1taulovmodKolding.Model.PUTEST.red.Value = true
	game.Workspace.PUsignalspor1taulovmodKolding.Model.PUTEST.green.Value = false 

That is the script that should change the value of the signal where the signals light should've changed in the script, but it doesn't seem to work. Still new at scripting. Any help would be appreciated
