Bulb Failure: Dipped Headlights or Rear Lights

[Pasteurised]

Hey guys, so ive got the "Bulb Failure: Dipped Headlights or Rear Lights" symbol showing up on my dashboard.

Ive checked all the lights and they all work, but the passenger headlight looks to be aiming a lot lower than the drivers headlight.

Do both lights share the same leveling sensor? If so that would indicate that its the passenger motor that is a fault?

Any help appreciated.

Quick update:

Ive discovered that sometimes only 1 dipped light will come on when i turn the lights on, but it alternates which side, sometimes both come on fine, its totally random.

i also get this occasionally, one xenon will fail to fire up. switching lights off and on usually cures this and puts out the warning. tired ballasts? need to get mine sorted, but as always there are other things on the list to do first...
