6 Volts or 12 Volts?
Like the standard ELO ignition, the one proposed here has the curious characteristic of having 6 volts for the main lights but 12 volts for the direction indicators. Piaggio has also used this technique on other vehicles (e.g. the Vespa PK50S), presumably to speed up the response time of the flasher relay at low speed (at idle).

Voltage regulator?
The often read information that a voltage regulator is needed for the alternator is incorrect. This is a so-called self-regulating system. This means that adequate resistance is given by the load of the users (lamps). If all consumers are connected as intended at the factory (yellow cable 6V/15W driving light, 6V/4W rear light), a voltage regulator is not necessary. However, this only applies to engines that do not rev significantly higher than a standard engine. Regulated motors, which usually reach much higher final speeds, can produce a significantly higher voltage for the same consumer load, with the risk of burning out the light bulbs.

12 Volt lighting on 6 Volt coils?
A coil basically only ever produces one power (watt), not a precisely defined voltage (volt). The number of volts always depends on the connected load (user) and the induced voltage (pole wheel speed). The load is defined by the light source. A 12 Volt bulb has a lower internal resistance than a 6 Volt bulb. Therefore, 12 Volt lamps can work without problems even on a system designed for 6 Volts. However, the risk of overvoltage is even greater, resulting in bulb failure. The brightness depends on the power of the front and rear bulb. If necessary, try the combination that offers the best light output and does not tend to burn out at high speeds. Due to the high speeds that can be achieved, however, one faces the problem that bulbs of equal wattage that do not burn out tend to glow rather than glow at low speeds.

Solution
If you want to be on the safe side, use a voltage regulator from the start, such as the BGM6690 (for 12 volts). This way you get a nice bright light that doesn't burn out, despite an apparently only 6 volt system. If you also want to connect a brake light, you can use the brown wire. However, Piaggio has connected an additional resistor in parallel to the bulb to avoid overvoltage.


TIP: Professionals can also connect all the coils of the lights in series (soldered onto the base plate of the ignition) and thus have a very high light output which must be regulated by a voltage regulator. This means that conversions with high power consumption (electric water pump, large headlight, etc.) can be carried out without any problems.
