Cloning from lighting and setting parent?

clicked = 0
script.Parent.MouseButton1Click:connect(function()
	player = script.Parent.Parent.Parent.Parent.Parent
	if clicked == 0 then
		if not player:FindFirstChild("Car") then
			car = Instance.new("Model", Workspace)
			car.Parent = player
			car.Name = "Car"
		end
		script.Parent.BorderSizePixel = 2
		script.Parent.BorderColor3 = Color3.new(255, 0, 0)
		local addon = game.Lighting.cartestpart1:Clone() --change
		addon.Parent = player.Car
		addon.Position = Vector3.new(68.1, 5.79, 16.1)
		clicked = 1
	elseif clicked == 1 then
		script.Parent.BorderSizePixel = 0
		script.Parent.BorderColor3 = Color3.new(53, 53, 53)
		clicked = 0
	end
end)

I'm trying to make a button that adds an object/model to a truck. I can't get it to work. And I'm stuck

OUTPUT: 'Players.Player1.PlayerGui.CarShop.BackGround.ClickTest.Scri', Line 12 17:48:23.445 - Stack End 17:48:23.447 - Disconnected event because of exception

a = game.Lighting["Epic Dino Man"]:Clone()
a.Parent = game.Workspace.WHATEVER

Or if you just want to set its parent...

game.Lighting["Epic Dino Man"]:Clone().Parent = game.Workspace.WHATEVER

Please post the full output code, it shouldn't say just Stack End
