I haven't done anything with fogs yet - other than slap some lamin-x on them.
I have read that there is a smaller version of the projectors I use coming out "soon". Who knows when that will be. From what I have seen, they MIGHT fit into the fogs.
I'm a bit "weird" when it comes to fogs........I honestly don't see the point of projectorizing them. Fogs are meant to be right in front of you, not throw the light as far as a projector does. I guess I'm just odd - I don't see the point of spending the money (lots of money!) on a projector setup in the fogs. I mean.......we are talking.......almost as much as a set of headlights. Only difference, fogs are cheaper and don't need a harness to run HIDs.
Get a set of OEM ones, and if you are looking for a LOT more light - HID them boogers. Get you some lamin-x to help with the rock chips (clear).
