The SAE Rigid's are awesome lights *if* you can aim them down. But, you wont be able too. There is virtually no adjustment. And, they are HEAVY! Mounting sucks. Two shallow holes in plastic using screws. You will get flashed all the time and they will shake and rattle on trails. Anyone that says otherwise is in denial.
No first hand experience with Bajas but I hear even the weakest ones are too bright for the streets.
Morimoto bulbs have some dumba$$ electric fans, motors that are loud and I imagine will die the second they get wet.
KC replacement housings/bulbs (led) in amber suck. Insufficient ammount of dark light. Can't speak for the white ones.
Bottom line? There no really good replacement for our fogs out there that I know of yet. Someone correct me.... I'm still looking.
