Hey Guardian
HID is High Intensity Discharge - think of it as a permanent spark rather than a glowing filament. Lot's of filament (i.e. ordinary) are described as HID and then you find in the small print it says "like"
The confusion also comes as they are marketed sometimes as Xenon and as Xenon is a Halogen gas so some companies that put xenon in the normal bulbs make big words of the xenon.
Put simply you need a special box per bulb (ballast) to generate the 20000v to start the spark in a proper HID lamp so if you see a HID/Xenon and it is a very small box with just two bulbs in it then it is quackery.
eg real thing
eg marketing waffle
The other thing is that you need to ensure you get the right sort of bulb. If you're upgrading your std jobbies then it is probably a H4, you need to get bi-xenon H4 as this will give you HID on both low and high. You do need to get the beam pattern setup correctly as a crappy beam pattern will still be a crappy beam pattern just brighter and more annoying to other drivers...

Not sure why you put all the info about e-mark etc, because unless you have self levelling HID's or self levelling suspension you are running with an illegal light set-up.
Get involved in an accident where the third party claims they were blinded by your lights and your be up shirt creek without a paddle.

and HIDs H4 bought through E-bay but they cost me £150 for kit and bulb replacements are about £40. The HIDs I'm using are dual filament there are a lot on E-bay Cheaper but only give dip beam. HID is 3x as bright as a 55watt Halogen and uses only 35watts(E' Approved).
I have found I needed adjust them slightly lower than standard and also give them a regular clean to avoid blinding people coming the other way.
Vehicles Made before 1983 there are no control on lighting
Vehicle made from 1983 to 1991 you can fit higher wattage bulbs to an E' approve lens (E' approved there should be E in circle at the bottom of the lens)
Vehicle Made after 1991 Need both E' approve Lens and Bulb
E' approved bulb are 55watts single filament (H1, H2, H3 spotlights) and 60/55watt dual (H4) (if memory serves me correctly the high wattage is actually for dip beam)

Are they dual filament or do they have the solenoid in the back? I'm asking as I've seen some with HID low beam and a Halogen high beam, but not for a while now.

Similar to http://www.hids4u.co.uk/product_details.asp?id=332
They are actually dual beam not the is pretty similar to that of H4 Bulb the only difference is they are slimmer to make the actual bulb about the size of the filament of the Halogen which keeps the beam pattern.

That is in actual fact a grey area. This requires vehicles manufactured with HID to have Both self Leveling and Self cleaning Headlamps. That does not include aftermarket I am now aware of some manufacturers fitting at dealerships (as it classified as aftermarket) because there was not enough room for the self - Leveling motors.
