Review on 2 Pack Active Piezo Buzzer Alarm - Electronic Beep Buzzer, DC 3V 12V 24V, 100dB Tone Alarm Ringer, Continuous Sound by John Wells

Revainrating 3 out of 5

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
