A cheaper solution to replacing the bulb on some BMW "Angel Eyes"
i got this bulb to replace the blown bulb in my BMW (3 series E9x) angel eyes. The manufacturer wants you to buy a very overpriced whole unit which has one of these bulbs inside it. You have to melt a plastic weld (use a soldering iron) to dismantle the lamp unit after removing from the car but it's not hard and well worth the effort.
