I bought the H1 f16 series for a projector style assembly due to my passenger side going out. Install was perfect, quality and design of unit is also exceptional. My only problem and disappointment is that mine don't seem to be very bright compared to my previous set. Even the kiddo said something when we went for a quick lil test drive tonight. I may end up buying something else but I'm not sure yet. Other than that they operate and are good to go.
