Decided to click the Amazon link today and order some stuff. I have a 1999.5 XJ and was looking to replace all the lighting that comes on when the doors open and the map lights with LED. I found 428 bulbs in my kick panels (looks like an 1156 with much smaller glass) and 906 in my map lights and sure I bought the right one in the dome light. If you googled 428 bulb you wont see my bulb. The only mods done before I bought my 99 was 4 speakers and a radio. I ended up going with 4 led tubes to light my floor and if I dont like them they go in my Civic.
