Ricky Bobby:

Yes, I unplugged the entire light assembly and swapped them side to side. I did swap just the bulbs and igniters at first, but, well, the situation escalated…

From what I can tell, there are at least 5 modules to control the lights. Good to know about the ALC module location. I was thinking that's where it would be, but it's good to have confirmation.

How many modules does it take to change a light bulb on a BMW?
