Be aware that the fitting of HID lights is now an MOT failure unless you have washers on your headlights and levellers on your front dampers.
No, this isn't quite the whole story.
It's rather complicated, but the manual doesn't reject HID lamps where they have been fitted on an older vehicle. ProComm is much closer to what the manual actually says (are you an NT Procomm?) is that if a levelling device is fitted, along with washers they much function; there is no prescriptive term that they must be fitted with the appendages mentioned above.
From the NT's perspective providing the colour and aim are correct on a vehicle using an aftermarket kit then there is nothing in the manual to allow a rejection.
http://www.motinfo.gov.uk/htdocs/m4s01000701.htm Is the page from the latest edition of the manual to my knowledge.
BUT does this make fitting HID lamps on an older car legal, well, this comes down to an entirely different set of regulations covered by 'Road Vehicles (Constrution and Use) 1986' legislation.... I'll just post a link for you to digest that:
http://www.legislation.gov.uk/uksi/1986/1078/contents/made
Essentially, there is nothing to reject them in the MOT manual, but it must be remembered that an item that passes an MOT does not necessarily make the vehicle compliant under C&U or the RTA.
Lamps show a great example of this in action here, if headlamps are not fitted to a vehicle this is not a reason for rejection (providing the vehicle is claimed to be used during the hours of daylight) however once that vehicle is driven on the road and smoke blows across the carriageway (hypothetical I know) and you can't turn the lamps on.... You guessed it, you're in contravention of the RTA... Vehicle is unroadworthy in that instance, but has an entirely valid MOT pass recorded.
To clarify:
- If required by law your vehicle must have a valid MOT certificate.
- An MOT certificate does not confirm roadworthiness.
- Roadworthiness is goverened by legislation in turn by circumstance.
**phew**
Basically, yes they'll pass an MOT, but don't confuse this with them being 'street legal.'
Also, I believe (but am not certain) there is a revision to an EU regulation (I don't have the time to find it, but feel free to do my research for me!) which makes self-levelling lamp and headlamp washers a mandated item to vehicles fitted with HIDs made after x-date. 2008 rings a bell, but I could have dreamt that.
