Why does this GetChildren lightswitch not function?

Lights = game.Workspace.LightsModel:GetChildren("Light")
local lightActive = false

script.Parent.MouseButton1Click:connect(function()
    if lightActive == false then
        Lights.PointLight.Enabled or Lights.SpotLight.Enabled = true
    lightActive = true
    end
end)
script.Parent.MouseButton1Click:connect(function()
    if lightActive == true then
        Lights.PointLight.Enabled or Lights.SpotLight.Enabled = false
    lightsActive = false
    end
end)

I have a large amount of Lights in a model, I believe I did this wrong, but this is the general idea. There's SpotLights in some and PointLights in some-I believe that's my main issue. Any solutions?

Combine both anonymous functions!

Lights = workspace:WaitForChild("LightsModel")
LightsTable = Lights:GetChildren()
-- ":GetChildren()" is one of those methods that DO NOT have a parameter. It just returns an array of all of the child(ren) from the given instance

isACTIVE = false

script.Parent.MouseButton1Click:connect(function ()
    if isACTIVE then
        for i, Part in pairs(LightsTable) do
            if Part:IsA("BasePart") then
                for i, Light in pairs(Part:GetChildren()) do
                    if Light:IsA("Light") then
                        Light.Enabled = false
                    end
                end
            end
        end
        isACTIVE = false
    else
        for i, Part in pairs(LightsTable) do
            if Part:IsA("BasePart") then
                for i, Light in pairs(Part:GetChildren()) do
                    if Light:IsA("Light") then
                        Light.Enabled = true
                    end
                end
            end
        end
        isACTIVE = true
    end
end)

Use the generic "for" loop to iterate over every value of the LightsTable array.

:IsA("") is a method that returns the class of the object.

As you can see, I went into extreme measures into checking if there's more than one light objects in a part, just in case, because I do not know what your descendants of LightModel looks like.

This script, of course, can be shortened to increase efficiency.

Lights = workspace:WaitForChild("LightsModel")
LightsTable = Lights:GetChildren()
-- ":GetChildren()" is one of those methods that DO NOT have a parameter. It just returns an array of all of the child(ren) from the given instance

isACTIVE = false

function Switch(Boolean)
    for i, Part in pairs(LightsTable) do
        if Part:IsA("BasePart") then
            for i, Light in pairs(Part:GetChildren()) do
                if Light:IsA("Light") then
                    Light.Enabled = Boolean
                end
            end
        end
    end
    isACTIVE = Boolean
end

script.Parent.MouseButton1Click:connect(function ()
    if isACTIVE then
        Switch(not isACTIVE)
    else
        Switch(not isACTIVE)
    end
end)
-- "not" reverses the boolean value
