From inside to outside of the headlight assembly (left to right in your pictures)

Module 1 - Daylight Running Lights (DRL) only
Module 2 - High Beams and Cornering Lights
Module 3 - All Low Beams (called dipped)


I've had to replace Module 2 on my left headlight as the cornering lights were out. (high beams worked)
I've had to replace Module 2 and 3 on my right headlight as it developed a leak and water shorted the modules. Only the DRLs were working

Module 2 and 3 have identical housing, but are 'keyed' differently so they only fit within their proper spot.
