The problem is obvious: there is water in one or more parts of the electrical system. Water and electricity do not mix.

The solution is altogether less easy. Every single electrical connection in and around every single light needs to be opened, cleaned, and dried. That includes any plug connections on the wiring loom. If should go without saying that any water inside the light fittings also needs to be drained to ensure the problem does not reoccur.
