I purchased these for a friend who had just gotten a Cahon (Cajon / sit-upon drum) and wanted to rig it for amplification. As many people know, piezoelectric transducers can act as microphones as well as tone emitters; they are especially effective at picking up percussive sounds. These are working well for that purpose.

They worked great. The easiest way is to remove both of the front turn signal headlight assemblies and wire one to each side . It is the easiest most foolproof way of doing it. Just tape it to one of the wires because they are so small they're not going to go anyplace.

Used these for a science experiment modeling how telegraphs worked with my kids. I'm thankful that it came in a two pack as the first buzzer did not work. I put in the second and it worked fine. The sound is quite high pitched, my kids even commented on the shrillness of it and how they wouldn't want to listen to it all day.

Loud. Installed on Evolution Golf Cart to remind driver that the turn signal is still on. Taped over the speaker area to reduce the volume.

I read the reviews where one of them worked and the other didn't. But in my case BOTH of them didn't work!It's not worth the hassle of trying to return them.
