My fading light stops after first fade? [SOLVED]

I'm making a light that fades out, then back in a blinking pattern using TweenService. It fades out, but it won't fade back in. How do I fix this?

TweenService = game:GetService("TweenService")
info = TweenInfo.new(2,Enum.EasingStyle.Linear,Enum.EasingDirection.In,0,false,0)

local changeVal = .8;
local changeVal2 = 12;

Light = TweenService:Create(script.Parent.SpotLight, info, {Brightness = changeVal})

Light:Play()

Light.Completed:End()

Light2 = TweenService:Create(script.Parent.SpotLight, info, {Brightness = changeVal2})

Light2:Play()

Light2.Completed:End()

There is no such thing as Light.Completed:End(). Replace it with Light.Completed:Wait()

I've figured it out, just a quick adjustment.

TweenService = game:GetService("TweenService")
info = TweenInfo.new(2,Enum.EasingStyle.Linear,Enum.EasingDirection.In,0,false,0)

local changeVal = .8;
local changeVal2 = 12;

Light = TweenService:Create(script.Parent.SpotLight, info, {Brightness = changeVal})
Light2 = TweenService:Create(script.Parent.SpotLight, info, {Brightness = changeVal2})

Light:Play()

Light.Completed:Connect(function()Light2:Play() end)
