I buy basic H11 bulbs for our '15 forester. I had one burn out and I stopped for a replacement and there were no basic bulbs on the shelf. So instead of going to another store I just grabbed a pack of sylvania xtravision H11 bulbs. They appeared to be just 1 step up from the basic bulb so I thought it would be about the same as what I had purchased before. Shortly after replacing the bulbs I started to notice oncoming drivers flashing me, often enought to make me think something was wrong. Drove past the dealer and had them check the headlight alignment. When I described the issue they said "we hear this alot". They drove around back and when they came back they said the headlights were aligned properly. They checked said they check it against a line on the wall in the garage. Headed out to get a new set of basic bulbs to see if the problem goes away. Just wondering if anyone has had a similar experience.
