Teds indicators should be self-cancelling but I think I got the optional non-self-cancelling type

Occasionally I forget to flick the indicator stalk back and drive on oblivious to the two green flashing lights that are gently reminding me to switch them off. The flasher unit is mounted in the engine bay and there's no way I can hear the distant click, click, click with the engine running so I had a fiddle

And came up with this little beauty

Just a simple relay mounted on an old tobacco tin lid 'amplifier' and wired between the common connection on the flasher unit to earth, all tucked up behind the dash. Works great with a nice distinct click

Probably eventually need to wire it to a siren the way my hearing is going

I've got the same non-self-cancelling indicating system on Harvey so I think I'll fit one in there too, might try a spray can lid resonator this time - or maybe an empty treacle tin
