I had my former XJ8-l programed at scott jaguar. I think it cost about 125,00. All it does is run the headlights full time.
If you're wanting something more interesting for drl, check with Mina gallery in California or Adamesh in UK. They may have some aftermarket drl and their quality is great.
I added drl rings to my 02 XK8 but the lenses easily remove on the X100 headlights. Not sure about the X150.
