I just bought some Osram H7 day breaker bulbs for my E87. In my haste to fit them I neglected to take note of the position of the old bulbs. When I fitted the new ones I think I was signalling to aircraft and really upsetting oncoming vehicles so I assumed I'd fitted them upside down so I turned them around and now they appear to be shining much too low. I couldn't feel a secure 'lock' putting the bulbs in and they seem to fit in any position pretty much.
My question- what is the natural position of the 'lug' on the H7 - should it be pointing 'up' or 'down'?
