so that the built-in locking safety mechanism is not "locked" when you receive it.
If the safety device does somehow become locked you can unlock this security system, located inside the socket on the side, with a small screwdriver. Please see our tutorial page for videos on how to unlock these light bulb sockets. And If you attempt to unlock the socket you must have the power
