Reminder Beep for Turn Signals

[5th_bike]

OK I'll try:

L ------|>----P------<|------R

L = wire between switch and left turn signals
R = wire between switch and right turn signals
(don't cut these wires, just tap off them)

--|>--- = wire and diode

P = red (positive) wire of piezo buzzer. Connects to the 'downstream' side of both diodes.

Black piezo buzzer wire goes to ground.

OK I'm too lazy now to draw how I would do the relay to keep it quiet when in neutral.

Great Idea. I put a 95 db siren set under the seat on my bike. Works well in town but on the highway you still can't hear it. But then on the highway.....who needs signal lights!!!! Just Kidding.

I tried this and I can't hear a thing unless the bike is idling. Even then, it's not very loud. If I take the seat off and cup my hand around the buzzer, it sounds a lot louder, but that doesn't really help. :tongue: Anyone else have trouble with this?

What dB rating of piezo speaker did you use? You might want to try reversing the wires on them also.

I used the 273-059 76 dB buzzers.
I wired them as described in the first post, but I'll try reversing them if you think that will make them louder.

CRAP!
I am embarassed. Thought I went back and changed that. Sorry.

I too found that 76 dB isn't loud enough. Should probably get the 85 dB model, 273-060. There are louder ones but I suspect they would be obnoxious when standing still.

I will now go back and change the original post.
ANOTHER EDIT: Check your installation after a few rides. I found mine were not secured tight enough and the vibration had started rubbing the insulation off one wire.

Also for anybody who has done this already:

no problem, at least they weren't expensive :biggrin:
so the 273-060 buzzers are loud enough?

That is an ASSumption, as I haven't actually tried them yet. :roll:

Moving them around a bit might help with the sound projection too. They draw almost 0 current so the wires can be extended to any length desired.

PS Don't bother switching the wires; they are polarity sensitive. Switching the wires results in ZERO dB! :biggrin:

It was just a thought.

OK, so here I am talking to myself again! :roll:

Haven't got the louder buzzers yet and had a different idea a few days ago.
If I can find some LEDs that will work at 12V. (maybe with a resistor added), I might experiment with a "light extender" this winter.

The idea is to tap into the bottom of the socket with the signal light in it (pretty easy, I've done that before) and then run a thin speaker wire up to something like my windshield bracket and mount a couple of LEDs high enough that you would notice them even in the daylight. If that works, you wouldn't need buzzers at all. The buzzers can get kind of annoying when you are sitting still. Need 2 LEDs connected with opposite polarity because of Zuki's wierd wiring of the indicator light.
