I jet wash the car to find out later on my front right dip head light, right fog light, right rear indicator, front right indicator and the left rear side light isn't working.

Any ideas what the story is here?

Forgive the apparently silly question, but was it just the outside you washed? I ask because it has been known for jet washers to be used in the interiors.

No I just used it on the outside. I sometimes jet wash the edges of the to doors but I didn't this time. I hope the bulbs aren't blown. 

Clearly water has got in somewhere, but unless you can see a wet patch inside it is anybody's guess where. Perhaps the most likey entry point is around the bonnet. I would start looking at the fuse box which is at the back of the engine bay, and close to the bonnet edge. Its lid is hard to clip on and may not have been secured properly.

Hello John,

Did you jet wash the car the last time you washed it? 
Kind regards,

Gareth.
