They are legal if fitted as original equipment on cars.

The status of aftermarket HIDs has been clarified for cars and light commercials since the January 2012 revision of the MOT test regulations (they are illegal and will fail an MOT), but it�s still a very grey area for motorcyclists.

Motorcycle HIDs are regarded as being illegal, but no law actually states they are. Provided they are correctly aimed and pass that part of the MOT test then the tester is obliged to pass you bike. Here�s the catch though; just because you have a valid and current MOT it does not mean you bike is legal - clear as mud?

Direct quote from VOSA�s �Matter of Testing� (publication for MOT nerds) in April 2012 regarding Motorcycle HIDs�

�Due to the adverse affect on the beam pattern, it is not considered legal to convert conventional halogen headlamps to HID xenon using the existing lens and reflector. Fitment of complete HID xenon headlamps is permitted, although the lamp may still be required to have some form of
self levelling system to be legal. In either case, there are currently no reasons for rejection in respect of motorcycle HID headlamps, providing, of course, that the headlamp aim requirements are met. If you are unsure whether a lamp meets the MOT test requirements, you can email VOSA at enquiries@vosa.gov.uk or, if the test is already underway, call 0300 123 9000.�
