Curvy headlights not working

See this post (specifically the 3rd paragraph), it outlines all the wires and components involved, including, but not limited to the left hand switchgear.

Assuming yes, then as you've dismantled it, you will have noticed that the headlight switch is two pole and there are two supplies to the switch, supplied and fused separately.
Clearly one pole is supplied and is switching correctly, (the one that supplies the tail, position and clock lights), and one may not be.

As both low and high beam do not work, and, if I understand you correctly, everything else does, then the fault is overwhelmingly likely to be in the parts of the lighting system common to both high and low beam, the relevant circuit is;

Orange wire from loom to right hand switch multipin plug - right hand switch multipin plug male/female connectors - orange & red wire from multipin plug to headlight switch - switch - yellow & white wire from switch to right hand switch multipin plug - relevant right hand switch multipin plug male/female connectors - yellow & white wire from right hand switch multipin plug to left hand switch multipin plug - relevant left hand switch multipin plug male/female connectors - yellow/white wire from said multipin plug to dip switch - dip switch.

Note on the right hand switch plug the supply wire is orange on the loom side of the plug and orange/red on the switch side

Check for voltage at each point along that line, if you don't have a meter a bulb with leads on it will work fine, put the wire from the bulb's body on a suitable clean point on the frame or preferably the battery negative terminal, the other wire is your test point, touch it on to the relevant points of the circuit as outlined above, if it lights you have voltage. Regularly check your tester back at the battery positive to avoid errors.

If you take the time out to investigate properly you should be able to repair the fault for next to no money. If you jump to conclusions this can take a while.

It's not as hard as you think it might be.

Edit, if you see the additional post here it shows why those wires are common and why they are important:

So not completely different but probably different enough to prevent a swap without some messing around.

OK. I am not very good at electrics and these schemes look very hectic to me but I will try and figure things out. Thank you very much for the help

I had this problem on my pointy a few weeks back... it was the LH switchgear connector into the loom! it had previously shorted/burnt and had been bypassed with a crimp terminal which had failed!

I started the bike today and the lights were working ...but during the ride they stopped working two times and then started again. Weird.

Sounds like a connection somewhere is a bit dodgy!

Look at the connector blocks in the points above. Give them a wiggle, this will not get better on its own
