Modern Vespa

Installed a Kisan Technologies head light modulator (Universal Heavy Duty). It works good. Easy to wire up behind the fairing. There is plenty of room there to mount the small unit. First follow the instructions starting on page 134 of your owners's manual (Correction: there are 4 "E" screws). Then you only need to cut the colored wire going to the high beam bulb, put two spade connectors on it, and mate them to the spade connectors of the unit. The unit's ground wire comes with an O-ring connector which I attached to a nearby mounting bolt.

The only tricky part was getting the Daylight Sensor to daylight. I fed a wire through the handlebar from the righthand side, then down the steering column. This takes patience and a bit of luck. I then taped the Daylight Sensor to the wire and pulled it up and out the end of the handlebar.

My luck ran out with the turn signal beepers. I chose to connect them to the rear signals, because I was afraid of moisture and corrosion if I connected to the front signals. Mounting is easy enough. But the beepers I bought (Radio Shack #273-060, 86db) are not loud enough in that location. I can not hear the beepers on the freeway or in heavy street traffic.

A few months back I installed a Kisan headlight modulator on my MP3 250. Within a week, while riding through town, at 25 mph, a guy started to pull out in front of me. His window was down and I said "hey buddy" pleasantly. He said back to me, pleasantly, your turn signal is on. My turn signal wasn't on but right or wrong my right headlight was modulating and could be mistaken for a turn signal. I removed the Kisan and wired the "both headlights on" modification.

Couldn't you leave the mod. on and still do the both lights on hack?

I have the both head lights on mod and a modulator. The modulator only modulates one light at a time. If low beam is selected it modulates the low beam. If high beam is selected it modulates the high beam and low beam is on steady. Of course if there is someone in front to see the modulator the high beam should not be on.

I have received a turn signal on comment but definitely feel I am seen better so I will keep the modulator.
