In the 1950's certain European cars had a selector switch that allowed one to use a friendly "city horn" that was a little more considerate for pedestrians and parking lots.

That said, the very few times I've used the 928 horns, they proved woefully inadequate. I put in the Bad Boy horns but they aren't that big an improvement. Having them inside the enclosed wheelhouse muffles the sound significantly.

Meanwhile, the quoted Cali sound standards mention a 200' "audible" distance, but make no mention of the distance at which the 110 dB(a) limit is determined. So long as they are consistent with the 200' measuring distance, no worries. Reality: I no longer live in the Great and Socialist Republik of California, although I do drive there. Plus, if the horn is used as intended (not in crosswalks...), I'd rather discuss the horn sound with the judge than argue the accident repair costs. Plus, that "city horn" switch would easily and instantly validate the "who, me?" claim for the officer. It's all hidden from view in the wheelhouse area, right?

Use a Sheissco lawyer, and we have nothing to worry about.

True. I installed 2 of the Bad Boys in the 928 also, which makes the volume decent

Yup...there’s Randy just tooting his own horn again...

Yea, that is classy, Randy.

But useful for those abusers that park in fire lane right next to the supermarket entrance. Mount it on the passenger side for max effect, pull
s- l- o- w- l- y abreast of the guy sitting in the car while the "mrs" picks up her lisinopril and give 'em a blast. Good way to get shot around here.

Yeah considered doing a relay setup - would definitely deliver more amperage and be even louder - but using the original 12V wiring harness is still pretty frickin' loud and very easy to set up.

I did a little research on this and came to the conclusion that this is not for me.

First of all: Are they really 150 db? If so they are way too loud. A gunshot is 140 db and anyone who forgets to put their ears on while shooting doesn't do it twice. 10 db is a 100% increase in power. 928sg - you are probably lucky if your ears aren't still ringing.

Second, it is not just California but almost every state that has laws about how loud a horn can be. I saw that on trainhorns.us (who knew?) which would be expected to adopt the most favorable legal position. In Massachusetts it's probably a felony, like jaywalking.

It's all fun and games until someone puts their ear out.

Sensible approach. I am a little horn-happier - in fact it is a huge source of frustration to have to find those stupid little buttons on the airbag wheel before I can let other drivers know my thoughts.

Not sure about the trucks but it might be due to federal regs.

Just remember to count to two after the light turns green............

Anti-social behavior extends from the interwebs to the real world again, all rejoice!

These might be a more reasonable option at 115 db and they have a deep old caddy sound. There are other higher pitch options as well.
