Is there an easier way for this script to turn on multiple lights?

I have a script that can turn on multiple lights in-game by clicking on a switch. However, I was wondering if there was an easier way to turn on the lights without needing to change each line of code when adding a new light. Here is the script:

local Light = script.Parent.Light
local Light2 = script.Parent.Light2
local Light3 = script.Parent.Light3
local Light4 = script.Parent.Light4
local Light5 = script.Parent.Light5
local Light6 = script.Parent.Light6
local Light7 = script.Parent.Light7
local Light8 = script.Parent.Light8 -- I don't want to keep repeating the same line of code each time I add a new light.
local Light9 = script.Parent.Light9
local Light10 = script.Parent.Light10
local LightSwitch = script.Parent.LightSwitch

local LightPart = Light.LightPart
local LightPart2 = Light2.LightPart2
local LightPart3 = Light3.LightPart3
local LightPart4 = Light4.LightPart4
local LightPart5 = Light5.LightPart5
local LightPart6 = Light6.LightPart6
local LightPart7 = Light7.LightPart7
local LightPart8 = Light8.LightPart8
local LightPart9 = Light9.LightPart9
local LightPart10 = Light10.LightPart10

local ClickHere = LightSwitch.ClickHere.ClickDetector

local SwitchA = LightSwitch.SwitchA 
local SwitchB = LightSwitch.SwitchB



ClickHere.MouseClick:connect(function() -- Function to turn on lights
	if Light.LightPart.SpotLight.Enabled == false then
		Light.LightPart.SpotLight.Enabled = true
		Light.LightPart.Material = Enum.Material.Neon
		Light2.LightPart2.SpotLight.Enabled = true
		Light2.LightPart2.Material = Enum.Material.Neon
		Light3.LightPart3.SpotLight.Enabled = true
		Light3.LightPart3.Material = Enum.Material.Neon
		Light4.LightPart4.SpotLight.Enabled = true
		Light4.LightPart4.Material = Enum.Material.Neon
		Light5.LightPart5.SpotLight.Enabled = true
		Light5.LightPart5.Material = Enum.Material.Neon
		Light6.LightPart6.SpotLight.Enabled = true
		Light6.LightPart6.Material = Enum.Material.Neon
		Light7.LightPart7.SpotLight.Enabled = true
		Light7.LightPart7.Material = Enum.Material.Neon
		Light8.LightPart8.SpotLight.Enabled = true
		Light8.LightPart8.Material = Enum.Material.Neon
		Light9.LightPart9.SpotLight.Enabled = true
		Light9.LightPart9.Material = Enum.Material.Neon
		Light10.LightPart10.SpotLight.Enabled = true
		Light10.LightPart10.Material = Enum.Material.Neon
		
		LightSwitch.SwitchA.Transparency = 0
		LightSwitch.SwitchB.Transparency = 1
	else
		Light.LightPart.SpotLight.Enabled = false -- Function to turn off lights
		Light.LightPart.Material = Enum.Material.SmoothPlastic
		Light2.LightPart2.SpotLight.Enabled = false
		Light2.LightPart2.Material = Enum.Material.SmoothPlastic
		Light3.LightPart3.SpotLight.Enabled = false
		Light3.LightPart3.Material = Enum.Material.SmoothPlastic
		Light4.LightPart4.SpotLight.Enabled = false
		Light4.LightPart4.Material = Enum.Material.SmoothPlastic
		Light5.LightPart5.SpotLight.Enabled = false
		Light5.LightPart5.Material = Enum.Material.SmoothPlastic
		Light6.LightPart6.SpotLight.Enabled = false
		Light6.LightPart6.Material = Enum.Material.SmoothPlastic
		Light7.LightPart7.SpotLight.Enabled = false
		Light7.LightPart7.Material = Enum.Material.SmoothPlastic
		Light8.LightPart8.SpotLight.Enabled = false
		Light8.LightPart8.Material = Enum.Material.SmoothPlastic
		Light9.LightPart9.SpotLight.Enabled = false
		Light9.LightPart9.Material = Enum.Material.SmoothPlastic
		Light10.LightPart10.SpotLight.Enabled = false
		Light10.LightPart10.Material = Enum.Material.SmoothPlastic	
		LightSwitch.SwitchA.Transparency = 1 -- This is just for the switch animation.
		LightSwitch.SwitchB.Transparency = 0
	end
end)

Here is what it looks like in Workspace: https://prnt.sc/t7spg3

Use for loop and table

Put all the lights inside a Folder or Model (I prefer folder) , which you can create on the explorer window, and put all the lights inside, just to keep things clean

local Lights = theFolder:GetChildren()
 -- This will put every reference to all objects inside the folder in a table
local isOn = Lights[0].LightPart.SpotLight.Enabled 
-- This will be used to determine wether the lights are on or off
local ClickHere = script.Parent.LightSwitch.ClickHere.ClickDetector
local SwitchA = script.Parent.LightSwitch.SwitchA
local SwitchB = script.Parent.LightSwitch.SwitchB

ClickHere.MouseClick:connect(function()
	if isOn then -- Check if its on
		isOn = false
		for _, v in pairs(Lights) do 
		-- Loops through the "Lights" table, if you are not sure how for loops works, go watch 			YT videos on it, there are tons
			v.SpotLight.Enabled = false
			v.SpotLight.Material = Enum.Material.SmoothPlastic
		end
		SwitchA.Transparency = 1
		SwitchB.Transparency = 0
	else
		isOn = true
		for _, v in pairs(Lights) do 
			v.SpotLight.Enabled = true
			v.SpotLight.Material = Enum.Material.Neon
		end
		SwitchA.Transparency = 0
		SwitchB.Transparency = 1
	end
end)

Use an in pairs loop. This will loop through a table of whatever objects or values you provide. For example:

local playersTable = { -- table
	
	"Zyleak",
	"UristMcSparks",
	"Stickmasterluke"

}

game.Players.PlayerAdded:Connect(function(player)

	for i, v in pairs(playersTable) do
		if player.Name == v then
			player:Kick()
		end
	end

end)

You can place anything in a table. In this example, I was providing strings which would be used to identify players who I want to ban from my game because these are their usernames. Of course, it is much better to use their Roblox ids instead of their usernames but I just want this to be easier to understand.

On line 11, i means index. The position place of an object in the table is their index. The index of "Zyleak" is 1 because that is the first object in the table. The index of "UristMcSparks" is 2. Finally, the index of "Stickmasterluke" is 3. v, however, means value. The index shows where an object is in the table, but the value is self explanatory I guess. Value is value. It's whatever it is. Then, I told the loop to loop through the playersTable by placing it as a parameter in "pairs". After this line, you can do whatever you want to each value it loops through. I made it loop through the playersTable to check if the player's name was one of the string values I provided in the table. If it does match one of the string values, it will kick that player.

Now for your situation, loop through your table of lights as well. This is going to be more complicated though because of the names you gave each object. I will explain what I'm doing in comments.

 ClickHere.MouseClick:Connect(function() -- Function to turn on lights
    if Light.LightPart.SpotLight.Enabled == false then
	Light.LightPart.SpotLight.Enabled = true
	Light.LightPart.Material = Enum.Material.Neon
        for i, v in pairs(script.Parent:GetChildren()) do
	    if v.Name ~= "Light" then -- making sure it's not Light because we already changed Light. I couldn't add Light in the loop because it doesn't have a number so this part would error
	        local number = string.match(""..v.Name, "%d+") -- finds number in the light's name
	        local childName = "LightPart"..number
	        v[childName].SpotLight.Enabled = true
		v[childName].Material = Enum.Material.Neon
	    end
	end
        LightSwitch.SwitchA.Transparency = 0
        LightSwitch.SwitchB.Transparency = 1

    else
        Light.LightPart.SpotLight.Enabled = false -- Function to turn off lights
        Light.LightPart.Material = Enum.Material.SmoothPlastic
        for i, v in pairs(script.Parent:GetChildren()) do
	    if v.Name ~= "Light" then
	        local number = string.match(""..v.Name, "%d+") -- finds number in the light's name
	        local childName = "LightPart"..number
	        v[childName].SpotLight.Enabled = false
		v[childName].Material = Enum.Material.SmoothPlastic
	    end
	end
        LightSwitch.SwitchA.Transparency = 1 -- This is just for the switch animation.
        LightSwitch.SwitchB.Transparency = 0
    end
end)

Remember to capitalize the C in Connect, as just "connect" is deprecated. Feel free to fix this script if needed, and if you have any questions, I'll try to answer as soon as I can.
