is it possible to get aftermarket xenons for the G55?

The other problem is that new laws in the US make it basically illegal to add Xenon headlights to a vehicle that was not designed to use them. There was a good H4 Hi/Lo Xenon upgrade offered that worked in the G-Class, but it is no longer imported to the US because of these strict new laws. See if you can get a set from outside the US.
