Transition old to new, new male With the help of this transition (approx. 15cm cable) you bridge between old and new contacts. This transition is used to connect a fixture or cable with an old connector into a new cable, light sensor or transformer. The male plug has two round recessed pins and the female plug has one flat and one round hole. LED Garden Plug & Due to updated EU directives, Play has received new 12V connectors on the cables (see product images). For old systems that are supplemented with new ones, this transition therefore exists.
