Quite a few of us have. Personally, I order from superbrightleds.com . At first, they were horrible quality (only lasting a few months) but the last set I got from them has been awesome. They've been in the car for over a year with no issues. Most of the bulbs, if not all, are 168/194.
Yes, and they're great. I got mine from Corksport, a Mazda specialist company. You can get them from a lot of sites, like Matt suggested. A well worth it upgrade for little money.
Be sure to reference Oznium. They're products are substantially higher quality than most of the competitors.
Just checked out superbrightleds.com and see that they also carry H3 bulbs for the foglights. I'm not sure if anyone else runs into the same issue, but I'm forever replacing the fogs as they burn out - maybe getting jarred by kicked up rocks or something being so low to the ground. I wonder if these would throw useful light and not burn out so quickly? Anyone with LED fog experience?
i got them off a vendor on nasioc, i think they're a little too bright. a lot of people that get into my car notice the brightness from the dome light right away.
