LED tailights and markers?

[Ben824]

so ive seen a lot of these LED replacement lights that fit in the place of the factory bulbs and i was wondering if anyone has tried using these in an XJ's tailights and turn signals? i want to try this in my 97 XJ so im really wanting to know if they fit in the 97+s. i wanted to see if these work becuz i recently noticed how crappy the lightin is in the stock tailights so i want to brighten them up a bit without changin out the stock tailights
