Things might well change in the future. In the EU Philips and Osram have manufactured LED Bulbs for replacing halogen Headlamp bulbs in reflectors. These have passes very stringent EU rules for homologation and come I understand with qualifying paperwork for specific vehicles. Unfortunately that will not legalise them for here anytime very soon but it sure to come, after all if someone from the EU comes over here with these bulbs that are legal in the EU are the authorities here going to prosecute them here, I am not quite so sure. Each country within the EU has little things that other member countries might not have but generally each accepts new legislation ans we would have done had we remained however I suspect that their will be some latency in following suit. I have written about this somewhere including reference to particular bulbs but not very good at searching sometimes.
