Update for future searches and those who give a ****:
I pulled the light and the amount of water that came pouring out of the Control Box and Ballast was.... hilarious? As you guys all predicted, everything below the light was gummed up with water.

Here's the main board from the Control Box. I ordered a new
Adaptive Light Control Box from ECS. Two questions:
1. Does it come with all new boards, because as you can see in the pic below, the circuitry is all rusty and likely shot? [EDIT: I looked a bit more closely at the photos of the new board and it looks like it does indeed contain the new boards]
2. I've been reading it needs to be coded to the car. Will the lights at least work and I'll still get the
△ Adaptive headlights! error? Or, will the lights not even light until I get the new Box coded?
