AW11 No headlights

This morning I noticed my headlights on the AW11 has stopped working. The popups go up but the lights don't turn on and I don't get a high beam light in the dash when I turn on the high beams.
 
I have recently been fiddling around with some minor wiring under the steering wheel so perhaps it's related to that?
 
Anyone got any ideas? I'm not that great with electronics.
