Indicator flasher relay -OEM QUALITY 3-PIN 12V 10/21W AC- Vespa PK S, PK XL, PK XL2, PX EFL (1984-), Cosa, Cosa FL, T5 125cc, APE

Inexpensive aftermarket flasher relay for all Vespa with alternating current (AC), such as all PX/PK Lusso models.
The relay does not contain electronics for rectification and is therefore only suitable for AC.

It has 3 connections:

The current is alternately clocked to L1 and L2. This achieves the alternating clocking of the front and rear turn signals. The purpose behind this is to reduce the on-board load to a minimum so that the turn signals still cycle properly even when idling (with little voltage from the alternator).

TIP: Due to the electronic control of the turn signal, it is also perfectly suitable for handlebar end turn signals or similar. In contrast to a mechanically controlled relay (such as the round DC sheet metal relays of the PX old models) then also turn signals with less load (e.g. if only 10W bulbs are used) clock.
The turn signal switch is then simply connected to L1. L2 can, but does not have to, serve as an output for a turn signal control light.
