How would one go about making a light switch tuning on multiple lights at once?

Before i explain, No this is not a request, i am not requesting for anyone to create a script for me.

I am a beginner scripter so I'm not very knowledgeable in terms of using Lua. I've watched multiple tutorials on how to make a light with a switch, however, none of them have really gone about explaining is and how it could tun on multiple lights at once. If someone could give me some steps I could take in order to accomplish this I would really appreciate it since I'm at a loss of where to even begin.

script.Parent.ClickDetector.MouseClick:connect(function()
	if game.Workspace.Light.Light.PointLight.Enabled == false
		then
		game.Workspace.Light.Light.PointLight.Enabled = true
		game.Workspace.Light.Light.Material = "Neon"
		game.Workspace.lsw1.Union.Transparency = 1
		game.Workspace.lsw1.ls2.Transparency = 0
	else
		game.Workspace.Light.Light.PointLight.Enabled = false
		game.Workspace.Light.Light.Material = "Plastic"
		game.Workspace.lsw1.Union.Transparency = 0
		game.Workspace.lsw1.ls2.Transparency = 1
	end
end)

To work with one or more Instances at once, you’d usually use a table. Then applying a special Loop to this table to traverse through each Instance, and amend the property accordingly. It would look somewhat like so (I will be using a KeyPress related Event to switch on the Lights)

local UserInputService = game:GetService("UserInputService")

local lights = {
   workspace.Light1, workspace.Light2, workspace.Light3
};

UserInputService.InputBegan:Connect(function(InputObject)
  if (InputObject.KeyCode == Enum.KeyCode.E) then
    for _,light in ipairs(lights) do
       light.Enabled = (not light.Enabled)
      end
   end
end)

I hope this was easy to understand, if not please comment and I’ll justify, good luck! Remember to accept and upvote if this helps!

This is an example, don’t expect to plug this in and have it work, instead you’ll have to configure this to be compatible with your desired end-game.

Alright this should work, its a bit complicated looking since the light components are in 2 locations, we have to run pairs twice to get both. As long as the lights are parented correctly - game.Workspace.Light.Light for the lights, and game.Workspace.lsw1 for the other components, it should be ok. If you have any errors try to correct them, if you cant let me know.

script.Parent.ClickDetector.MouseClick:Connect(function()
	if game.Workspace.Light.Light.PointLight.Enabled == false then
		for i, lights in pairs(game.Workspace.Light.Light:GetChildren()) do	
			lights.PointLight.Enabled = true
			lights.Material = "Neon"
		end
		for i, lsw in pairs(game.Workspace.lsw1:GetChildren()) do	
			lsw.Union.Transparency = 1
			lsw.ls2.Transparency = 0
		end
	else
		for i, lights in pairs(game.Workspace.Light.Light:GetChildren()) do	
			lights.PointLight.Enabled = false
			lights.Material = "Plastic"
		end
		for i, lsw in pairs(game.Workspace.lsw1:GetChildren()) do	
			lsw.Union.Transparency = 0
			lsw.ls2.Transparency = 1
		end
end
end)
