I recently replaced my H7 for the first time. Used a Sylvania bulb which appears to be the exact bulb that was installed at the factory. There are 4 types of Sylvania H7 bulbs. Each a little brighter and whiter and ~+$3 than the previous. However, take note on the back of the package. The cheapest has an estimated service life of something like 230 hours. The next "upgrade" that drops to about 150 hours, then down to ~85 hours for the brightest and whitest.
It would seem that the Sylvania Basic is their "hard duty" version. If you most recently installed the super duper version (?Silver Light Plus?), then 3K miles is probably on par with the expected life. So far I'm sticking with the cheapest longest lasting 230 hours (ugliest yellow). With 17K miles on the original bulb, I'm pretty sure it actually lasted for considerably more than 230 hours.
Also the bulb loses brightness with age. In the beginning I recall being impressed by how bright the headlight low beam was. More recently before replacement it was adequate but not great. The new bulb is nice and bright again. Good thing I am running forward LED DRL's or I would have been stuck with no forward lighting and reduced visibility with an increased risk of SMIDSY. Maybe that warrants a routine replacement of the low beam? Every 15K miles?
I actually misread the receipt. It was at 146,600 km so about 18,000 km or about 11,000 miles ago.
They are Sylvania "Xtravision" which appears to be there lowest level.
No problem exchanging the burnt out bulb for a new one (at Canadian Tire.)
