I know there are a ton of threads out there about headlights so I apologize for starting a new one. I have an '06 R52 with stock Xenon HIDs. I noticed the driver side is noticeably dimmer than the passenger side. I also noticed that the driver side ballast has only 3 wires going to it (one is just hanging) and the passenger side has 4 wires. Don't know if that is the problem or not. I want to replace the bulbs anyway. Which type do I get? Also, I want to replace the halogen high beams with LEDs but I can't figure out how to get the darn things out. I've removed the dust cover and the connector. Now what? Any help is appreciated.
