After market HIDs are not illegal as long as they pass the beam alignment test.
Sorry, but that is absolute bollox.
Washers are also not a legal requirement when fitted after it has left the factory. The washers are only required on cars that are built in factories (so standard xenons that come with the car)
Again, bollox. Headlamp washers, and more importantly, automatic dynamic levelers are absolutely and categorically legally required. It is both a UK and EU legal requirement. Retro-fitting HIDs without the full OEM gubbins will invalidate the "Type Approval" for the car. This will then invalidate your insurance (even if you do actually declare it as a mod), and will also lead to potential criminal prosecution for a breach under the "Construction and Use Regulations", and a breach of CUR is also a breach under the Road Traffic Act.
You cant fail an MOT for something you do not have to test, a good example is the spare tyre in some cars; if its bold just take it out before the test, if they cant check its bold they cant fail you!
A spare tyre is NOT a legal requirement - otherwise how come all these cars with "tyre mobility systems" (a bottle of slime and a mini compressor, instead of any kind of "spare wheel") can pass an MoT!
Correctly functioning headlamps which comply with the manufacturers Type Approval ARE a legal requirement, and a testable item.
I have aftermarket HIDs and it flew through the MOT last week. Its now passed in a Honda garage and my local garage.
Then you have just admitted to not only an illegal car, but also a dodgy MoT.
