So my passanger side headlight went out and I plan on soon seeing whats the cause and if a replacement is necessary or something possible else. I was looking online to get an idea of how much a new bulb would cost and I saw FCP has a discount on BMW oem bulbs and a few other bulbs. I read that people tend to stick to Philips and Osram but if anyone has any experience, is there any reason besides cost to buy aftermarket over oem? The oem ones are more expensive but that is not a problem for me. Thanks for the help
