Hi, I just bought a 2003 ML500 demo for my wife and it didn't have Xenons.

But the deal was too good to pass up. So how do I put Xenons into the truck now? I searched and found one thread, but the link to it was bad. I am not so concerned about the hi beams being xenons, mostly concerned with the low beams. I have found a local supplier for a Catz system and the price is right, but I need to make sure there is not a simpler way to do it with MB or close parts.
Thanks in advance for any help.
