Ideal for Vespa PX models (up to approx. 1983) with battery where the indicators are powered by the battery. On these models both indicators (front and rear) flash simultaneously, the relay must therefore be able to switch at least 42Watt.
The Lucas relay also has a reserve of 5Watt for the indicator control light.
