Osram H7 Halogen Headlamp Bulb, Champion Germany Edition, 64210LCG, Limited Euro Football, Duobox (2 Pack).
From the specification page:http://www.osram.de/osram_de/produkte/lampen/fahrzeug-und-fahrradbeleuchtung/autos/halogen-scheinwerferlampen/light-champion/index.jsp?productId=ZMP_4053492
I judge this is the "re-coloured" version of the Silverstar 2.0 (judging from the bulb lifetime data).
Please note, the colour and temperature (in terms of colour, not heat) is not affected whatsoever by the gold/red colour ring on the bulb surface when the light is on. The colour ring is only visible when the light if off and when you have reflective type of headlamp and when there is no cap in front of the bulb.
