VT headlights dim

[bassplayer]

Hi, was wondering if anyone could offer any advice? After driving through *almost* flood water on my way to work, I noticed that the driver's side headlight had stopped working. Swapped it with passenger side, and they both worked, but very dim. Found ground near back of battery and cleaned, but no difference. I'm a bit stumped! Any help would be awesome. Cheers

I would be fitting new bulbs and checking relays.

check fuses also.
