Christmas lights swtich?

Or use an in line switch on the mains side- after all it is how they are intended to be used. Just make sure the cable grip is working well, if need be pack it out a bit.

I too am not keen on leaving the transformer energised with its load cut off by a switch, though I don't think it would come to any harm. Just one slight possible problem: the mains plug and transformer of a decoration light set are often incorporated as a single unit, so putting the switch before the transformer is not possible. I would not advise trying to put the switch after the control box, which selects the various flashing sequences, even if you could identify a common "return". So it's back to the other suggestions: remote controlled sockets, switched extension lead, additional socket installed. Pick which is most convenient.

 remember when these were all the rage ?

I certainly do. In the 1950s, and into the '60s, it was usual for decoration light sets to be sold fitted with a BC adaptor plug. Power sockets were sparse in those days, and it was assumed that the set would be plugged into a lighting socket fitted with a BC 2-way adaptor. I have still in use two twelve-20V-lamp sets and they still have the BC adaptor. I see no reason to change this; I have a dedicated lead with BC socket to power them. These big, bright bulbs harmonise well on the Christmas tree in conjunction with a modern LED set.
