Bayonet Inside guard socket. Push and twist to lock bayonet design means perfect contact to eliminate white lights. Also it is almost impossible for it to fall out during play.
The system works like a light bulb fitting. To insert the plug you have to push it all the way into the socket and then twist to lock. To remove the plug you should push before you twist to minimise wear to the plug.
