Best mod on an XJ IMHO is to do the headlight relay upgrade. Adds about 1 Volt at the lights which is A LOT in terms of light.
The dipped beams will be so much better, clearer cutoffs.
The high beams you could install some driving lights, they will throw light much further forwards in a narrower beam than the headlights,
