as bb says these have no on/of switch they are on all the time and it doesnt matter as they run off the lighting coil in the generator.i would say you either have a bad connection on the bulb holder either where the bulbs terminlas touch the holders tags or the wires themselves are corroded there.tell me does the rear light still work ok,not the brake light but the rear light when its running.

Ok..... I think I understand

All newer scooters now have lights on all the time. When you rev the engine the front light should get brighter.

You should have a high/low beam switch but thats probabably it. If all you lights have gone off and the engine is running rev engine they may just have got dim with the tick over.
Check back light as well. Sometimes someone helping is best as you can always see it in the day.
If you had lights and then no lights I would suggest a blown fuse. If its just one light thats gone, front or back then it will more than likely be the bulb.
Also do Horn, indicators etc work?
