Loud Turn Signals Save Lives!

This write-up was contributed by addicted, including all text and images.

An audible turn signal indicator is perhaps the one mod that should be on everyone’s scooter. I want you to have this mod. I want you to be safe. You need this mod.

I’ve given allot of thought on how to present this mod in a simple, and entertaining format. Then, I came to my senses and realized it’s impossible.

Parts Needed:
Radio Shack Piezo Buzzer, RS part # 273-080, $6.39
Radio Shack Diode 2-pk, RS part # 276-1101, $0.59

Time Needed:
1 hour

Skill Needed:
The ability to use a screwdriver, and cut and splice wires.

Patience Needed:
Not much.
No small parts, springs, etc.

Vespa ET-Specific Panel Removal Instruction
(To Illustrate The Ease Of Scooter Panel Disassembly):

•Pry-off Piaggio badge from horn cover
(hint: look for the screwdriver slot on the badge’s right side)
•Unscrew horn cover screw, and remove horn cover
•Unscrew 2 screws under horn cover, securing glove box tray
•Open glove box door, and unscrew 3 screws securing glove box tray
•Lift, and wiggle-out, glove box tray from front cowl. May require pressing-down glove box release as you wiggle the glove box
•Take a moment to bask in your worldly accomplishment
(Note: If you have a GT, LX, or PX and don’t know how to disassemble your panels, use a pry-bar, or just ask here and someone will help-out)

A Mini Electronics Tutorial:
The Piezo Buzzer, and the diodes, are polarized. They only conduct electricity in one direction. To maintain proper polarity, you’ll need to orient your scooter with the front pointing towards the North Pole (just kidding, you should point it at the South Pole). The Piezo Buzzer wires indicate polarity using color-coded red and black wires (ingenious). The diodes indicate polarity with a stripe on one end of their body. Be sure to connect the Piezo Buzzer and diodes in their proper polarity orientation, using the wire color or body stripe, as depicted in the stunning wiring diagram.

Working With Diodes:
If you are soldering your connections, it's suggested you shield the diodes from excessive heat. The usual way to do this is to attach an alligator clip in-between the lead you're soldering and the diode body. The alligator clip will divert some heat from the diode. I've never ruined a diode by soldering, and I don't always practice safe soldering either. Don't fret about it. They didn't cost you much.

Wiring Instructions
(Common to all Vespa models):
Look at the left and right signal lamp assemblies (Chinese folk can look from right to left, instead of left to right). You’ll see both signal lamps have a black wire, and a colored/striped wire. The colored/striped wires are the hot wires (ironically, they don’t feel hot), and the black wires are the ground wires. You’ll be splicing your Piezo Buzzer to both hot wires, and just one of the ground wires.

About The Wiring Diagram:
I struggled with the wiring diagram style. I finally decided on a pictorial diagram, as pioneered by the Aztec Indians. The wiring diagram is meant to be self-explanatory. Using the wiring diagram as a guide, wire-up your turn signal Piezo Buzzer.

How Do I Mount the Piezo Buzzer?
I mounted the Piezo Buzzer with double-sided foam tape, positioned centrally on the back of the front cowl, just bellow the horn grille. If you don't have any double-sided foam tape handy, you can buy some at Radio Shack.


In Conclusion:
There you have it. In your haste to go riding, don’t forget to reassemble the panels. Beep, beep.

We tried the same set up on our LX150 Vespa but now the front turning lights just stay on but without blinking at all. And the buzzer also stays on continually even when the light switch is off. We tried the switch L then R and no blinkers go off and the buzzer keeps beeping.

What went wrong?

Thank you

Hi ya'll we fixed the problem. We had connected the wire to the two front white light on the front of our LX150 Vespa. Those lights are not turn signals at all. They only have white light to be more visible. That is why the buzzer stayed continually on. Somehow we thought that they were turn signals.

We kept everything the same way then from there attached a long red & long black wires going all the way to the two tail end turning signals and connected each wire to each light. All is working fine now when the turn signal switch is engage for either R or L and the buzzer is off when the switch is off.

BTW thanks for sharing this. Now we will feel safer when the buzzer goes off during rush hour or while passing cars along with our LOUD horn.

A quick tip for those installing buzzers using diodes - ground the buzzer via the output side of a brake light switch - then when the brakes are on the buzzer mutes. Saves lots of irritation when waiting to turn at stop-lights etc.

Wouldn't it be easier to connect the buzzer to the output side of the circuit interupter and just use one wire. Of course, I do not have a wiring diagram of the system to see if that's possible.

Jim, do you have a diagram or photo of this for dummies?

Has anyone tried this solution? http://www.scooterwest.com/items/?_pageCCS=t#page=/item_details/Audible-Turn-Signal-Flasher-for-2010-AND-NEWER-Vespas/9564 I know it's more money, but it looks like it might simply swap out the factory flasher unit with no splicing or diodes needed.

Can I install 2 piezo buzzers (1 on Left and 1 on Right) without the Diods?

I did this on mod on my MP3, but Scooter West has the Plug in Module you can buy for $29 bucks for the Modern GTS/GTV that adds the "Click Noise" which I like a lot better by just replacing the Relay under the Knee Pad.

Yep, did this on my PK.
Simples & you know which signal is flashing.

Just test buzzer location to make sure you can hear it riding before final mounting. I know this from experience and it's useless if you still leave your turn on cuz you can't hear the buzzer with motor noise, traffic and your helmet on.

This post inspired me to patch into the tail turning lights' wiring and install the diodes right before a vibrating motor that came in a plastic box about half the size of a deck of cards. It's mounted under the seat using a ziptie threaded through two 1/4" holes in the plastic. Now the seat shakes unmistakably at each flash of either one of the signals.

I used one of the bolts holding the seat hinge to the frame for a ground, so only needed to tap into and run two wires around the engine - the one on each tail light that wasn't black.

The vibrating motor was $10 and a pack of 10 diodes was $5, all on Amazon Prime. I had various 16-gauge wire, disconnectable butt connectors, and splicing connectors, lying around anyway. 18-gauge wire would probably be done too. I'm a terrible solderer and didn't use a heatsink, so the diodes got plenty hot. Didn't matter.

This device could take 5 or 6 watts versus about 1 watt for a small buzzer. So it might affect the flasher unit which may only be rated for 20 to 30 watts. Did you notice any difference in speed of the flashers?

I wondered about this too but there is no detectable difference - at least to me.

I'm new around here and didn't want to say anything, but yeah, I was surprised too.

It works great. But I pretty much never go straight through intersections any more. Turning is just so...stimulating.

Please appreciate the extraordinary restraint I have exercised by suppressing the customary Kiwi sheep joke.
