My G is almost 15 years old and has about 320000km on the clock I drive the vehicle now almost 10 years and have been driving since the 260000km always with switched on lighting and since to a large extent also in the dark is a good lighting a lot worth but lately I had the feeling that the BiXenon burners so slowly lose their luminosity therefore I have replaced the illuminants with new ones now what if you compare the old with the new ones quite sense gemac The change was not a big problem if you once understood the function of the holding ring which connects the burner with the reflector, if one half is open you have to turn the bulb a quarter turn to the left then you can take it well…
