From my own vehicle experience whether cars or scooters, if a sectioned light fails its usually the local earth to it or the positive line has broken in between switch and device, if all the lights have failed its usually a general earth or a main live feed problem, the mentioned stator wire problem is usually the cause of such as yours on a Vespa where the stator out grommet has broken and the wires have chafed, another area for Vespas was at the steering joint where chafing would cause merry hell with the loom, could that be an issue on a Lambretta?
