Any water get near the connections Graham? i know mine are after market but i had the same problem, i just needed to dry one of the connections and they have been fine ever since.
Yeah I reckon one of the ballast packs got soaked.
It's drying now at home.
Not sure on bulbs I'll swap them tomorrow.
Can you buy those kits anywhere in Dublin?
I'd just buy a set tomorrow and be done with it.
