LED bulbs on very very dim when switched off

[Velascas]

Hi all, I bought some E14 LED bulbs and when I switch them off they still emit a little light. There is no leak from the switch. I found out that a few friends also have the same issue.

Any ideas why this could be happening?

induced voltage from adjacent cable/s. a small device called a snubber across the L and N of the LEDs may cure the problem.
