Hi, the problem you are having is with the switch itself, this is a common problem so the switch is not expensive to buy.

once you replace the switch the lights will work as normal.

if it was just one light not working then you could say bulb if the high beam wasnt working then you could say it was fuse or relay but as you have high beam this would rule out them being the fault.

now the only other problem it could be is a wire so give the wires a bit of a wiggle at the back of the head lights then give them a try if they then work you may need to do some soldering to fix a loose wire but if they still dont work then this would suggest the switch itself is at fault.

let me know how you get on or if you need further assistance ok
