This subject has been discussed to death!
People can make all the arguments - "mine don't blind people", "I've never been flashed by oncoming traffic", "other people fit them", "mine are "e" marked", etc, but the fact is that after-market HID's fitted to Puma headlamps are illegal, period.
If your Puma is fitted with an HID conversion, you must be able to answer "Yes" to the following questions (and you can't!) for them to meet the legal requirements:
Does your Puma have self-levelling headlights or suspension?
Does your Puma have headlamp cleaning?
Are your headlamp units (outer lens, reflector, bulb) type approved to ECE 98 and "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).
"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."
