Hi,

Leaving your indicator on is a real worry in an open car such as the Haynes Roadster, road and wind noise mean that you can’t hear the flasher unit. Here’s a simple circuit that gives you an audible warning a bit louder than the “tick tick” of the flasher unit.



The parts are available from Maplins

Piezo buzzer – part number FL40T

Diodes – part number QL73Q

No doubt electrical types will be able to come up with a better circuit, maybe incorporating a timer or some way of stopping the buzzer when the hazards are on? I could see that being very annoying!

Cheers

Chris
