I'm wanting to get a louder horn for my 1300, found a self contained air horn that's VERY loud, but I would like to be able to keep my stock horn too. Has anyone set up a delay circuit, so I can do a simple beep beep, before the air horn kicks in, you know, if someone is asleep at a light I can beep beep, but if they're about to hit me on the freeway I can let the big horn wake them up. I'm thinking maybe 3 seconds of regular horn then air horn honks, something like that
