I like Zounds "Eco-Blast" air horns. However, they are not very reliable.
I waited until the temp was up to forty degrees, to give it a fair chance . Hisssss... Nothing.
And it's my third Zounds horn.
My Lowrider has a 12 volt 7 amp/hour battery, so I went to the NAPA Auto Parts Store and bought a generic car horn.
I mounted the horn on the bottom of the fairing. I had to move it forward to avoid rubbing the tire.
I wired it in parallel with a 115 Db piezo alarm. It is really nice and loud now.
I was afraid the Piezo alone would cause a problem, because the law that requires a horn or a bell on a bike specifically metions sirens and whistles as being illegal.
The switch is a push button, but not momentary. I have to click it on, and click it off. My question is; is the pushbutton legal, or should I get a momentary contact that opens the circuit when I lift my finger?
