How do i tween a NumberSequence for a Beam?

i am trying to make controllable lights with tween i made some without tween but i want to make one with it. the surfacelight and transparency works but i cant get the beam to change with it. is it possible to make the bean tween transparency?

Here's the script i made its located in a TextButton

    for i,v in pairs (game.Workspace:GetChildren()) do
    if v.Name == (script.Parent.Parent.Parent.name1.Value) then


local gui = script.Parent
local ts = game:GetService("TweenService")
local child1 = v.Main.LED
local child2 = v.Main.LED.SurfaceLight
local child3 = v.Main.LED.Beam
info = TweenInfo.new(0.5)-----amount of time to tween

local goal1 = {}
goal1.Transparency = 0

local goal2 = {}
goal2.Brightness = 1

local goal3 = {}
goal3.Transparency = NumberSequence.new (0.5,1)


script.Parent.MouseButton1Click:connect(function()

    ts:Create(child1,info,goal1):Play()
    ts:Create(child2,info,goal2):Play()
    ts:Create(child3,info,goal3):Play()


end)
end
end
