Car Reversing Warning

[wetterfugal]

Can anyone supply a circuit of a one second pulsed out put to a relay that activates when the reversing lights are on? This I could use to opperate a sounder.

Try googling for "555 tutorial".

I tried to buy a piezo buzzer at a car parts store but they just had some that go in the reverse light socket and the bulb goes into it. That should work but not as much fun.

I tried to buy a piezo buzzer at a car parts store but they just had some that go in the reverse light socket and the bulb goes into it. That should work but not as much fun.

I put one of these on my SO's car about 10 years ago. The buzzer/sounder still works but I am unsure about the lamp itself.

The problem is that the thing is not loud enough. If one hung the buzzer/bulb outside or under the car it would be fine. But the lamp haousing mutes it too much. YMMV
