Hello, I was shown by some drivers several times today, which is why I checked my headlights. The right day driving light bulb is defective. Before that I stood with my local car-trader and looked at what they have. Among other things there were “Xenon-White” H4 halogen lamps on the shelf, supposedly up to 30% better light yield etc. I decided for the normal H4 standard and this already built in. Since with the day driving with my W124 eh not so satisfied I wanted to ask if these pears actually bring an improvement of the luminosity? And above all, of course: what about safety? They will be allowed – but do I blind the oncoming traffic more than usual or noetig?
