I have BMW Led fogs, they are alright for short range wide spread light or as daylight running lights and that is about it. I think the halogen yellow light would be better in fog but these stock led`s came on the bike.. About the same goes for the LED headlights, good to be seen but not for distance.As soon as I can find an LED spot that outperforms the FF50`s that is the way I will go but until then its FF50`s for distance.
