Try fitting a bulb in the fitting before you fit it to the scooter, and check that the two prongs make a good contact with the pins on the bottom off bulb. Sometimes, the prongs can even touch each other, creating a short ciruit.
It's easy to check now, but not so easy to check when the housing is fitted to the scooter.
