Nach einigen Jahren werden die Xenon Scheinwerfer immer schlechter. Bald kann man kaum mehr etwas sehen.
n ilonaHier ist ein Trick, um die Lichter wieder vollständig vorzubereiten. Die Lichter wurden entfernt, die Xenon-Lichter wurden entfernt. Jetzt mit einem spritze , pro ca. 5 ml Isopropanol in den Glasspiegel herein geben, dabei den Scheinwerfer so halten das der Spiegel gerade ist und nichts heraus läuft. Nun ca 20 Minuten warten, das isopropanol verdunstet und der Scheinwerfer kann wieder eingebaut werden.

Das Ergebnis ist wirklich sehr erstaunlich

From Google translate:

After a few years, the xenon headlights get worse and worse. Soon you can hardly see anything anymore.
n ilonaHere is a trick to fully prepare the lights again. The lights were removed, the xenon lights were removed. Now use a syringe to add approx. 5 ml of isopropanol into the glass mirror, holding the headlight so that the mirror is straight and nothing runs out. Now wait about 20 minutes, the isopropanol evaporates and the headlight can be reinstalled.

The result is really very amazing 2007 TD4 HSE

Well I didn't know this was a thing and only last night I was thinking that my headlights might not be quite as bright as they used to be.
Searching shows that there is even a YouTube video on the subject for the FL2.
