Plug in out
Using plugs can often be difficult. Sometimes they are so tight, its hard to pull them out of the socket. Sometimes its difficult to tell which plug belongs to which device and they are hard to find in the dark. This new plug design using different colors can help to some extent. First, the plug can easily be inserted and removed even from tight sockets with just one hand. Second, the different colors can be allocated to different devices, which helps users to find the correct plug quickly and easily. And third, in the dark, this new plug also emits a low light to make it easier to locate.
