(Legal) LED Question

So phillips makes homologated LED bulbs now, the Ultinon ones, and have a datasheet showing the information, including my exact car (Passat B7) being listed there with the year lining up.

The legality question has already been answered, however my question is whether the average garage will be aware that it is a bulb that corresponds to the halogen equivalent. Is it worth having the datasheet and other relevant info in a pamphlet on the passenger seat incase any questions arise?

I have missed clear-white headlights since selling my E-class earlier this year but I want to go about it legally, especially since I know how painful being dazzled by non-legal LED fits is.

Cheers chaps.
