For some reason, every now and then they illuminate (for a few minutes). Since dead bulbs and blown fuses (usually) don't come back to life and then die again only to come back again, I'm going to guess that the bulbs and fuses aren't blown (although I am not an expert).
The lights have illuminated two or three times in the last year.
Any clue on what could cause this behaviour?
Thanks!

First thing I would do is replace the bulbs. he vibrations will make them come to life now and then. (its also the cheapest thing to start).
The next thing I would check is the wiring to the bulbs while you in there replacing the bulbs.
