I got a set of the h11 lights for my wife's new f-150 but the heat sink is too large to fit in the housing and have adjustment. So I found that the company car I drive takes a h11 on the low beam with a projector. After tearing half the car apart I found that the light output was not very good. I don't know if the projectors are messing with it or what but they were disappointing. I love them in my fogs on my super duty now it looks like I am stuck with them and I don't want to modify the housings on the f150
