LED plug socket to show it is on

[gr1340]

I have recently changed my 4 port usb charger to a 6 port.
The old charger had 4 led lights to show each item being charged and was a nice visual reminder that the socket was on. The new charger does not have an led so I wanted to know if anything existed that would serve as a visual sign the charger was on.

What is there?

Even a double plug socket with led when on would suffice.
