if they come with the car from new (factory fit) then they MUST have self-leveling & washers - EU directive.
If you fit them yourself afterwards, usually by just changing the bulbs, then the following applies:
1. the lights are NOT to EU standards/directives so ARE ILLEGAL to use on public roads, only police or DOT inspectors (usually working with the police) can do anything about this.
2. they WILL pass a MOT as this only looks at the allignment & beam patteren, as long as these are correct the inspector can't fail it - even knowing that it's illegal to use on the road
Again this is for UK roads .... dont know for other areas
I've got a HID-bulb kit on my Leon and it's passed 2 (or 3) MOT's, will be in for it's next in a few weeks and i won't be taking them off for it

Im a Vehicle Examiner for the Department for Transport (VOSA).
Firstly we do not need the Police to stop vehicles, we now have an addition to are warrant which allows us to stop anything being used on the public highway.
Secondly at test the testers are also looking at the headlights to make sure they are a matched pair, they emit more white or yellow than any other colour and they ere secure.
Thirdly when it comes to EU directives and other laws there is nothing that I or the police can do for non standard (aftermarket HIDS) headlights fitted to a vehicle.
I work to 'The Caterisaton of Defects' (check out the VOSA website) when on the side of the road and there is nothing in there which says to look for EU markings when checking headlights or bulbs.
So in my professional opinion aftermarket HIDS are fine as long as they are within the standards set out at MOT.
Anyway im getting mine at the end of the month
