fwiw. re: the Philips h4 led bulbs:

"Safe road-legal H4-LED on the market worldwide

Approval of the Philips Ultinon Pro6000 H4-LED type by the German federal authorities means that drivers across the country can now legally upgrade their headlight bulbs from halogen to Philips LED lighting.

These premium Philips LED bulbs improve safety by boosting visibility and delivering a perfect beam pattern that illuminates the road ahead without dazzling other road users".

....seems like a valid upgrade!
