Could be a fuse blown? I think :confused: the fuses are under the panel to the right of the steering wheel..
 
but the other headlight works? is there a fuse for each?

Not sure, but I doubt it sadly :(

How about the wired connections, is there anything obvious.. a volt meter will tell you if your getting current.
 
There may be a fuse for each light. That way you still have the use of one headlight if the other side blew
