    Default HIDS - Department of Transport factsheet.

    Not sure if this has been posted before but just lifted this from another forum and item #2 makes for interesting reading:

    Fact sheet: Aftermarket HID headlamps
    December 2006
    In the Department's view it is not legal to sell or use after market HID lighting kits, for converting conventional Halogen headlamps to HID Xenon. If a customer wants to convert his vehicle to Xenon HID he must purchase completely new Xenon HID headlamps. The reason for this is that the existing lens and reflector are designed around a Halogen filament bulb, working to very precise tolerances. If one places a HID "burner" (bulb) in the headlamp, the beam pattern will not be correct, there will be glare in some places and not enough light in other places within the beam pattern.

    The following is the legal rationale:

    The Road Vehicle Lighting Regulations 1989 regulate the situation in the UK.
    Under these Regulations, HID/Gas Discharge/Xenon headlamps are not mentioned and therefore they are not permitted according to the strict letter of the law.

    However new vehicles have HID headlamps. This is because they comply to European type approval Regulations. The UK cannot refuse to register a vehicle with a European type approval. These are to ECE Regulation 98 (for the HID headlamps which are tested on a rig in a laboratory) and ECE Regulation 48 (Lighting Installation on the vehicle).

    For the after market, a used vehicle cannot obtain type approval because it is only applicable for new vehicles. However we feel that saying "HID is banned in the after market" would not be reasonable. Instead we should make analogies with new vehicles. It would be reasonable to require HID in the after market to meet the same safety standards as on new vehicles. The same level of safety should apply.

    Therefore a HID headlamp unit sold in the after market should:

    1. be type approved to ECE Regulation 98 as a component.

    2. when fitted to the vehicle should enable ECE Regulation 48 to be complied with (although no government inspection will take place).

    3. Comply with RVLR as far as "use" is concerned.

    In practice this means:

    1. The headlamp unit (outer lens, reflector, bulb) shall be type approved to ECE 98 and be "e-marked" to demonstrate this. That can only be done by the headlamp supplier - Hella, Valeo etc. who must test the headlamp in an independent laboratory.

    2. Once fitted to the vehicle it must have headlamp cleaning and self-levelling (which can be for the headlamp or can be in the vehicle suspension - some expensive estate cars have "self-levelling suspension" and that is adequate). Also the dipped beam must stay on with the main beam.

    3. The headlamp must be maintained in good working order, kept clean, and aligned/adjusted correctly like any other headlamp.

    Under the Road Traffic Act 1988 it is an offence to supply, fit or use vehicle parts which are not legal.

    In summary it is not permitted to convert an existing halogen headlamp unit for use with HID bulbs. The entire headlamp unit must be replaced with one designed and approved for use with HID bulbs and it must be installed in accordance with the rules stated above.

    Thats the beauty of the Veccy as most of the healight units have the projector lens.

    Regulation 2 is abit of a pain though.

    No m8, if you have manaual levelling on the headlight switch module in the car then they are not HID compliant.

    If you have auto levelling, self levelling suspension, headlight washer system and the headlight unit build for HID bulbs then thats where you can legally fit them.

    Maybe I should have been clearer in my post.


    I was refering to the headlight unit only. I know that these additional things are required - washers, self levelling. But are the actual head light units the same? Or if not, what are the actual differences.

    think the Xenon ones have ballast fitted and hence slightly bulkier at the back but not 100%.
