Strange lighting fault(?) which involves a child's toy.

[Rampage]

Bear with me.

Our toddler has got a toy which is a wooden board with cut-outs to put various shapes of wooden vehicles into. When the correct vehicle is put in the correct slot it makes an imitation noise of the particular vehicle. This toy is battery powered and doesn't connect to the 'mains' at all.

When we turn the lounge light off at night, it starts making noises. The lounge light is a compact fluorescent, which is around 3 meters away, the wiring for the switch is even further away and no wiring goes near where the toy is.
Any ideas?


EDIT: Just worked this out while posting it! I'll leave it unanswered incase anyone wants a guess.

now the best bit is still to come.

wait till they get bigger and they go into the big toy box called a loft.

one night all of a sudden when everyone was going to sleep I keep getting nagged at over strange noises. every time I went up stairs they seemed to stop and were intermittent.
one night I had enough of taking the normal nagging and went into the loft. turned out it was the wheels on the bus toy. must have had some dam good batteries in it as it had been going for months. every time I hear that dam song it drives me mad now

we had same problem with that damn yellow bus, the wheels on the bus go round and round, round and round arrrrrrgghhhhhhh!
