How can i toggle a boolean value?

I want to toggle a boolean value if someone clicks a button. I got it to work that if they click it will go on and stay on for 2 minutes. But i would like to toggle the value if they click, not just turn it true for 2 minutes. Can someone help me please?

local toggle = game.Workspace.EmergencyLight.Toggle

script.Parent.mouseClick:connect(function()
	toggle.Value = true
	wait(120)
	toggle.Workspace.EmergencyLight.Toggle.Value = false
end)

You can use

 toggle.Value = not toggle.Value

This line assigns the value of toggle to the opposite of its current value. Since a boolean only has two possible values, it is toggled.
