Lo ppl

Driving home tonight and suddenly my main beam went off and just went to side lights, so I switched them off on the light stalk then back on and they came back on, then they went off and havent come back on again only the side lights, is it my light stalk knackered?? , and when I pull back the stalk on the left side [as if to flash some one] just the passenger main beam light comes on..

car is a S1 Rst
