Hello, Our 2007 V8 has the ABL Xenon Projectors and they are starting to look pretty aged. We really like these and want to fix the flaking and cloudy look, can this be done or would they need to be replaced?
In my personal opinion, the best long-term approach includes a professional UV topcoat (spar varnish, 2K clearcoat) after the lenses are refinished. The off the shelf kits work fine (even those with the topcoat in the bottle) but the restoration does not last.
Before you restore them, you may want to check if the reflectors inside the projectors are burnt. Post number 27 shows the burn marks inside of the reflectors bowls of the projectors (see link below).
I have a 2007 and refinished them only to find out 6 months later the light output in front of the XC was diminished, A quick way to check this is shown in post number 41, of this thread, you should check it.
FYI - FCPEuro has the headlights (less ballast, but includes bulbs) for around 700.
Only problem is that early 2007's have a different ballast in what looks like the same outside housing (the early 2007's have a flat, 2 connector ballast where connectors are on top, where the later 2007 and newer ones have an oval shaped ballast, where there is one connector on the end of it. If you have the newer ballast, you can buy replacements and use your old ballast, but if you have the early 2007 ones, you need to buy a ballast plus the housing.
PM me with questions, I am going through this headache now (using fogs to get light right in front of car to make up for this deficiency)
newer ballast in new headlight replacements and later 2007 and up XC90s:
