This ia a genuine Piaggio item, it is the headlight unit that is fitted in the latest model PX and all models from 2001.
It will fit older model PX and PE but you will need to modify the wires on the unit by removing the block connectors and fitting the appropriate electrical connectors to match up to your original connectors.
On all models from 2001 onwards it is a straight fit.
Do not get this confused with india items that are also for sale on ebay this it the genuine item and the way to tell the big difference is by the lugs on the sides of the lamps that fix to your headset for securing the unit, Piaggio ones are metal and the Indian ones are plastic.
