for Vespa P80-150X/ PX80-200E/ Lusso 1??/ P150S/ P200E lens plastic yellow main&dipped beam socket: BA20d parking light socket: Ba15s w/o bulbs Grade B – decent repair Product description In general, the headlamp units from the most recent Vespa classic range are interchangeable. However, there are differences in the shape of the socket and in the used bulb. In this way, in the older PX models (up to 1984) a 25/25W bulb is installed, and in the newer models a 35/35W bulb installed. In addition to the ELMA and PIAGGIO versions with a real glass headlamp diffuser, a BOSATTA headlamp with a yellow headlamp diffuser may be delivered in order to achieve a complete MOD style. Anyone who wants even more light on their PX can either install the MY clear glass headlamp unit or alternatively that of the Vespa Cosa.
