I have been for many years with the pseudo-Xenon H4 lamps on the road and was very pleased with the, compared to standard H4 bulb, higher light output of bulbs. As now one of the Xenon Birbe broke and I no longer get kknnte the variety, I geducht to spare, and here found it.
After installation, I was eager to test the darkness by the lights. After switching on then the surprise! The light yield and distribution was still a lot better than I was accustomed already by the lamps "Xenon".
I can now, after I've tested the Leuchtmitrel 3 weeks, just to say that this is by far the Lucht Besre that I have so far been able to experience on a vehicle with H4 light. For me, it will be only in the future, these lamps. We will also switch the Fahrzerg my wife to these bulbs. More Security, we worth the investment!
