Welcome.
Light - You need to sand down the lights with some high grit (2000-3000) paper with water and polish up with megs plast-rx they come up brand new with the right amount of effort
Optionally you can fit the xenons easily with wiring adapters, it's plug n play with a few vcds tweaks, you just won't get the auto levelling but easy to do manually, simples
Faded black trim, best stuff is Gtechniq C4, you will be amazed they come up factory new mate.
You are welcome ;)
