Would really love to have some outdoor twinkling lights this year. During our house rennovation we had the electrician fit 3 outdoor sockets especially for this purpose but all the outdoor lights I have seen are fitted with transformers that are too big to fit in the waterproof socket boxes and are designed to be plugged in indoors. We have no opening windows at the front of the house in a suitable location so I'm lost as to how to set up outdoor lights - please help
