Any help on this would be very appreciated.

Dipped beam turns on when the scooter is turned on. So it doesn’t seem to be a bulb or fuse issue. However, as soon as I start the ignition it turns off. When the engine is running the dipped beam doesn’t work, nor does the high beam - however the passing beam does work (which is the same as the high beam - so I don’t understand why the passing beam works but full high beam doesn’t). If anyone knows the answer then it would be much appreciated.

It's probably not the dipped beam you are seeing. Many motorcycles/scooters have three lights:

  • Pilot/parking: this is a low wattage bulb which turns on when the engine is off, it gives you enough light to push the bike to a spot without draining the battery, and makes you visible at night. In some bikes it acts as a backup to the low beam, but not always
  • Low beam
  • High beam

Sometimes these bulbs are individually replaceable, sometimes the functions are combined into fewer bulbs and other times they may be integrated as a single unit, you'll need to investigate how it is in your specific case. It sounds like you may have a combined low and high beam bulb which has blown or you have a bad electrical connection to it. I'd check the contacts for contamination and clean them before replacing the bulb.
