Ive used led in my 1999 pathfinder fog lights also and they were not bad at all. they do draw low wattage so the fuse should not have blown and our fog lights aim can be adjust with the screw on the back of the housing.
about 2 years ago i switched to hid in the fogs and it was much brighter than the led.
you can also find cree led fogs on ebay too, they're are some good sellers that offer good warranty also
and they also recently started making cree led Headlights, but im not too sure how the output on that is as yet.
here is whay my hids look like:
the hids costs me around $30 per kit (bulbs and ballast) on ebay, i look for sellers that offer a return policy and warranty, you can choose either to have bi-xenon hid bulbs ($60) or single beam which is what i chose because they are just bright enough that i never have to use high beams. replacement bulbs costs me $15 if anything should happen
