Steve you missed the correct section for your question. You want the X308 section. Use the search feature there. If it is a common problem your question will be answered already.

No "auto" headlights on the X300 or X305 (XJ6/XJ12)! We actually have to pay attention to when headlights might be needed, and then flip a switch with our fingers. This also includes remembering to turn them off when parked. It takes a lot of mental and manual labor, but we have learned to deal with it. We believe it makes us stronger as a community. Such luxuries as "auto" headlights we can only imagine!
