It's the main beam. The light switch in the car seams pretty pointless to me as its positions are;
1. Off - Main beam & rear lights on (DRL), instrument lights off (expect for the needles which are red all the time)
2. Auto - DRL on, then when it gets dark the instrument lights turn on!
3. Side lights - Why?
4. On - Main/DRL on along with instrument lights.
With the auto option & DRLs what else is required?
