The H11 bulb seems to be a very popular bulb in many Japanese cars (but not my 2005 Subaru) in the low beam headlamp . I am curious if upgrading from H11 to H9 in a low beam projector is always a safe thing to do, with regards to glare?
Why is the H11 bulb seemingly so popular with vehicle manufacturers? Is it because of bulb longevity?
