. I was careful to buy the ones that sound like a car alarm

They make the sound (beeeeee) I was looking for after buying the ones that sound like a car alarm. I will use them as temperature and oil pressure alarms on the boat.

Pros
  • Quality construction
Cons
  • Communication with seller

Loud buzzer for 12 volt systems

This buzzer is made of durable plastic and beeps when 12 volts are applied to the wires. It is loud and can be heard several meters away. You can hear that above the engine noise. I used these beepers for motorcycle turn signals.

Pros
  • Nice packaging
Cons
  • Basically everything is fine, but...

Haven't done anything better in security and surveillance

Don't know if it was because the wires on the devices were so thin I didn't have a good connection or what but I could barely hear the buzzer even before I started the scooter. After the scooter was gone, they couldn't be heard at all. They stay in place because it's too difficult to pull them out.

Pros
  • Stylish and modern design
Cons
  • I vaguely remember

Loud enough but not too loud. Sounds more like a rumble

I bought these piezos because my truck's piezo died an unknown death behind the dashboard. Many times in 10 years I have left the light on after work. I connected the buzzer by simply using a tee that connected to the power wire on the headlight and grounded the other side. I attached the buzzer to the inside of the engine bay with thick 3M tape (grey) (cleaned the surface with some brake cleaner). Works great.

Pros
  • Weight
Cons
  • Not everything fits
