If you want help with the process of installing Xenon headlights, potential
helpers probably would want to know where you are so they know if you are
within a reasonable travel distance or not.
If you want an explanation of what it takes to install high intensity
discharge (HID) headlamps, I recommend a google search of "xenon
headlights."
Note that most of the aftermarket conversion kits are for export only and
not designed for use in the U.S.
There are blue-tinted bulbs that make the light appear to be HID.
The HID conversions basically involve mounting a ballast in the vicinity of
the headlamps and then changing the OEM bulb and wire harness over to the
aftermarket one.
