Cover for Car Cigar Lighter Socket

Cover for car cigar lighter socket

Cover the power socket in case there is no cigar lighter plugged in.
Typically, the cover prevent any light coming from the socket if there is any.

A string can be attached to ease removal.

I cover one to the three sockets of my multi-socket plug for esthetic reason and because I am afraid of something (e.g. a coin) dropping in the socket.
