Random. At one point or other they've all gone. I suppose there are a couple that are most frequent. We've got an open plan living and dining room that has seven wall lights and three centre lights in the spaces. The centre light in the dining room goes far more often than the two in the living room and one of the wall lights in the dining room and one in the living room go far more often than the others.

Chris installed a four way light in the toilet room and within a week three of them had gone. The three way light in the bathroom is currently down to two lights.

Some lights never go - the one at the top of the stairs, the ones in our bedroom and Zack's but Maddie's go quite often.

It's very random!
