It's Anti-Dazzle. Only optional with full LED package. It's the coding for auto-high beams. Normal operation in US is full on or full off if it detects cars. When you have Euro spec then the high beams can light up different parts of the road and create a tunnel around a car in front of you to prevent Dazzling the driver. It will also lower the driver side high beam if it detects oncoming traffic while still maintaining the passenger side high beam. Really amazing. Search this forum for Anti-Dazzle.
