Modern Vespa

I intend on getting a Signal Minder flasher/running light module from Scooter West so I can run LEDs and have a self cancelling blinkers. However, I see in the 2015-2016 parts manual that the OEM flasher is just a 2-terminal conventional flasher. I had attempted to find an electronic flasher that would run LEDs. The ones I called about from a reputable LED aftermarket company stated they would not work on the Vespa (plug and play). ( I am guessing the plug/terminals are reverse-they would not say). Anyone else experience this. I am just curious. I could make a electronic 2 or 3 terminal one work. It seems like this is just dark territory or something. Not much info.I do not see that the signal light wiring should affect anything with the ECU, so what gives?

Just add load resistors in parallel with the LEDs.

I do not like load resisters. I know many that use them, and have installed on customers vechices myself. Solid state electronic flasher units live a longer life, and are more efficient-along with the LEDS, of course, just my preference.

I fully understand 'efficiency' with respect to lamps that are on all the time - LEDs make very good sense there. But for turn signals? The plus point of LEDs is that they switch on and off very quickly, making them more visible. There's negligible 'minus' from using load resistors, the lamps are only on for a tiny fraction of the time the bike is being ridden.

You can get LED friendly solid-state flasher units that can be fitted to almost any vehicle, including Vespas. On the other hand, a couple of load resistors will cost less than $2...

The reason I am installing LEDs is because the Signal minder (that I will be buying in the future) is capable of making all (4) turn signals into running lights- when not in signal/blink/turn mode. Also the rear turn signals both flash (3) times when you apply the brake light. When I install that , there will be more power being used with conventional bulbs. Hence LEDs pull very little power. Untill I get the signal minder unit, I thought I would install a solid state LED flasher and use it -since I already have the bulbs.

This is Plug an Play, I'm using it on mine since I converted to the Euro spec light all around which required a relay that would work with two 6w bulbs rather than two 10 what bulbs.

It is the 2 pin flasher relay
