How I can make a Lantern per Battery duration? With Local Script ?

Hi, I need to make a Lantern with Battery. When you use the flashlight for 60 seconds turn off.

and to recharge when 10 seconds pass

1] I created a tool and renamed "Lantern"

2] Into "Lantern" I created a block called "Handle"

3] Into "Handle" (Block) I created a SpotLight called "Lightning"

4] Into "Handle" (Block) I created a LocalScript

MY QUESTION How I can make this script?

NOTE: I also need to do that when I clicked Turn on and off.

local location = script.Parent.Parent.Parent.Lantern
local Light = location.Handle.Lightning
local V = 60

-- Function On()
    -- for i = V, 0, -1 do
        -- ??? 
    -- end
    -- Light.Enabled = true
    -- 
-- end

-- Function Off()
    -- ???
    -- Light.Enabled = false
-- end
