(I tried searching but the search feature ignores H9.)
Trying to plan ahead in case my Fusion's original H11 halogen bulbs go out soon.
After some googling, I found this:

In short, you can modify H9 bulbs to replace H11s.
H9's are 65W and H11's are 55W.
H9's are actually brighter with more lumens and they don't blind other drivers if used inside projector headlight assemblies.
