    A thread on this topic was recently opened and closed before I could point out what the safety issue is.

    Apparently the powers that be no longer worry about keeping the hot leg buried as deep into the socket as possible. In Christmas lights these are side by side anyway.

    What is important is to fuse the hot leg. In a non polarized light string you will find two fuses, one in each leg so whichever leg is hot WILL be fixed.

    When you shave down polarized plugs to fit non polarized sockets you defeat this important safety feature.
