Am I right in saying that HID's are currently legal aftermarket fitment in the UK?
If this is so, and the same for LED's, if they are not legal in Germany would a tourist be fined/punished under the same rules? I'm thinking yes.
I'm suprised those are the regs in Germany, cos although I might be wrong, isn't there an Audi that has a bank of small lights that go across the front which I assume are LED's? They surely must be legal?
There are several cars now in Germany with daylight running lights in LED. If they are fitted as original equipment then they will be road legal. I am not sure this is the case with stuff bought on eBay or a supermarket like Asda's car bits & pieces section. If it has an E number, then it should be OK. If this is not stamped permanently in the glass, then you should ensure that you carry documentary proof that they are sold as E certified. These running lights are not just on new cars, but on boy racer and older cars also.
Unless the HIDs complete lamp assemblies (not just the bulb/electronic ballast) are marked on the glass that they have an E Number, then they are unlikely to be legal within the EU. According to German TÜV Nord, they are legal if supplied as a factory option by e.g. BMW. I think anything supplied by Touratech or Wunderlich will also be legal in the EU if fitted and used for the purpose they were designed for. Stuff from eBay is usually NOT E marked and when I have asked the sellers if they are, I am met by a deafening silence.
Different countries within the EU have their own E number (Germany is 1, UK is 11), so the testing authorities can tell where they were certified. Even Halogen H7 and H11 bulbs have that number on their base.

You can buy an uncertified bit of equipment (tyres, exhausts, shock absorbers, etc. etc. not just lights) and apply to the Government authority for approval for use on your bike, car, etc. However, this is likely to be expensive and time consuming.
As regards being prosecuted, I would guess they could stop you in Germany and if the policeman was feeling particularly anal, then could require you to change the lights and prosecute you (€80 and one point on your licence and they have a reputation within Germany of being less sympathetic that the UK traffic police). You probably want to carry spare replacement halogen bulbs.
I know that they do actually prosecute bikers with illegal HIDs. I did talk with another biker (who worked in a very well known

large biker Bricks & Mortar/Mail Order clothing & accessory shop in Germany) and he had an HID H4 bulb fitted, but got through the TÜV test as a 'friend' did it for him. I think he was just waiting to get stopped by the police on the road though.
One thing is certain, is that under German regs, only one Xenon HID is allowed (Factory fitted, Touratech, Wunderlich, etc. spot lamp). I was told that the lumen rating must not exceed 2000 lumens, but this seems low, as Les Wassell quotes (I think) 3500 lumens/HID 50W bulb. I don't think colour is critical, provided it is basically white (tungsten or bluish white). There was some mention of self levelling suspension, but when I said I had electronic suspension that seemed to be accepted. Certainly the BMW 1300GT and 1600GT bikes have the option of a Xenon factory fitted light (presumably high beam only).
While colour is not legally critical, if you are using high colour temperature bluish/white Xenon HIDs, they are rather obvious and so likely to attract plod's attention.
The UK seems more relaxed over enforcement of the e certification by police and MOT stations, but there is increasing talk on the forums that things may be about to change and vehicles will fail the UK MOT if fitted with non e marked products.
