Thanks for the reply, I'll try again when it's warmer out. I live in the DC area and of course I tried when cold, when it was in to 30's outside instead of today when it was in the 50's.

Hi, anyone replaced horn for hybrid version? I tried to do it follow the instruction and picture but unsuccessful. The placement of the screws are different and it doesnt move much after remove those plus headlight's

Thanks for any info/suggestion. Hate those dc beltway drivers and want to give them warnings with hella instead music to their ears. Haha

I'm new to Toyota, got my 2013 Rav4 Limited in Nov 2016 and I immediately thought the claxon sound was a joke.

So now that I replaced the low beam headlights for LEDs, my next project is to change the horns.
I'm glad I found this thread.

Owning a 2017 RAV4 XLE I was a bit embarrassed with the toy like horns! I also purchased a set of El Grande Fiamm 7411 off from EBay for $26.33 shipped. Thanks to the write-up and pictures from rscot01 I was able to complete the job with only one minor setback. Dropped the attaching bolt to the lower horns. That bolt disappeared into the bowels of the vehicle. Under the vehicle I had to remove one large piece of plastic trim, finally located the devil. The difference in the sound is night and day and very much worth the effort.

My many thanks to rscot01 for the write-up and pictures, made the difference.

Why would Toyota make higher tone horns? Is it cheaper and they are saving money? Do they not have the engineering knowledge to replicate a 1970's Cadillac horn?

The real answer is probably based on physics and human physiology.

Fact 1: sound transducers, which is what a horn is, are more efficient at certain frequencies. As a general rule of thumb, if you have say 10amp wiring dedicated to a horn, a horn transducer tuned to 1000hz will be louder than a horn transducer tuned to 700hz. Lower frequencies require more energy than higher frequencies for the same output. If you are limited to 10amps, you get more sound pressure output if you go with a higher frequency.

Fact 2: Human hearing is more sensitive to higher frequencies, up to a point, when it starts to roll off. If you have two horns, one 700hz and another 1000hz, and they both produce the same sound pressure levels, the 1000hz will appear to be louder to a human ear. That's why if you have a home theater system, at full blast your sub-woofer might require a 500 watt amplifier, and your tweeter will use only 20 watts.

So, the high sounding Toyota horn is beneficial in 2 ways, it generated a higher sound pressure level, and on top of that the perceived loudness of the tone is higher also. The horn is a safety device, not a macho fashion accessory, and I would argue that a Toyota horn is much better at grabbing the attention of other drivers.

You make a good point, but WHY does Toyota put normal horns on the Camry but meep-meep horns on the RAV4?

Help RAV4World members help you by providing your car's operating location in your profile page. Climate can cause a RAV4 in Dallas Wisconsin to experience a different set of issues when compared to the same model in Dallas Texas.

I would guess that that is based on what supplier is picked to provide parts for a model vehicle. And the supplier is probably using equipment that is decades old to make such a simple and unchanging part as a horn. And probably the tone of the horn was initially set by various regulations in various markets where the vehicle is exported to.

Are high tone horns that are common on European and Asian vehicles better? I'd say yes. Lower tones travel farther. That's why a ship or a train have a low tone air horn. High pitch tone at short distances is better as it has a higher intensity, but it won't travel miles.

Most situations where a horn is used are very short distance. As the point of the horn is usually to avoid collision. If someone is driving on the highway with the radio on, and starts merging into someone else, a high pitch tone has a better chance to be heard and distinguished over the low frequency highway rumble.

Just changed out the horns on my 2017 RAV4 hybrid limited using this post.
Worked great although scary pulling the top of the bumper loose.
Thanks much!
