The Toyota single horn was just the size of those fitted to Chinese scooters and i need a bit more noise to scare the birds on the Exeter Road as they eat the roadkill. A nice pair of Fiamm horns from a Jaguar XF arrived from ebay at under £10 so added a relay and additional fuse to power the new ones using the original wire to switch the relay.
Its a nice sound and not too loud so now i have to go out in the car looking for birds. Nothing changes does it.
