Interior Bulb Part Numbers
I have found that all sizes do not agree on the right light bulb part number for the XJ.   Autozone and many sites say that my dome / map lights use the 168 bulb.   I dont have loops on my factory bulbs.   Rather its a 44mm Festoon bulb with end sockets, the loops are useless unless you do some custom wiring.
