Hi Rick;
I must wholeheartedly agree with Sandi. Good drivers will get annoyed by loud horn as I do. Some will get scared, jump and cause an accident. For those who are careless and oblivious to their surroundings that horn was not configured yet. Thanks, "Boatdoc"

Check out the self-contailed air horns from Griot's Garage: Car Care, Detail Supplies, Garage Organization, Car Accessories - Griot's Garage 800-345-5789 . They have 3 to choose from starting at $39.95 to the new, 'truck sound' model at $69.95. They are rated at 139db at 4 feet and 116 db at 6 feet.

I have a set on my motorcycle, andlet me tell you, people REALLY get out of the way when I hit the horn button!

I'm not a fan of horns, I'ld rather "get and give" the finger and a few choice words. Most of the time I just ignore the idiots and drive defensively.

And if I ever got back to my campsite and found all my stuff on the hood- Well when I found the trespassers the last horn they would hear would be the one blowing taps.

Horns are so neglected these days...
Road rage would never have a chance if horns were used more often.

If you use your blinkers more than your horn, your risking all of our safety.

Truck Air Horns

I would like to install a set of truck air horns (not train horns) on our F250 and would appreciate feedback from forum members that have actually done so. I do not want roof top mounted horns.

Horn make, model, and source would be of real value to me. How well the horns have held up, sound level (too weak or too loud), etc. would be of interest.

I plan to install a VIAIR constant duty onboard air system on the truck. This system will serve a dual purpose. It will power the air horns, and it will provide a readily available source of compressed air for maintaining tire pressure while on the road.

Many thanks,

Train Horn

Probably a little more emphasis on defensive driving would be more helpful than an investment on a train horn installation.
Very seldom does a dedicated professional driver need to announce his presence with a loud horn. (although the temptation is there on many occasions.)
In most cases all the other motorists, and pedestrians, in the area have not seen what you have just witnessed, and only look at you as the idiot making the noise and assume that it is you that is in a rush to get somewhere.
Having said that - there is a time and place for everything!

Cadillac Horn

I too have heard of the Caddy horn being a good one.

I don't want to scare the pants off anybody - just get the attention of someone about to pull in front of a mass of metal that could be hitting them....

So I was thinking of adding a caddy horn with the current electrical wires to ADD some volume and get attention when needed.

When in the boneyard, which models (or years) would be best to ask for

Suggestions please !!! TIA

I, too, have been researching air horns. Sometimes, the OEM horn is insufficient to get the attention of a driver who chooses to text and listen to his Ipod while operating a motor vehicle on the highway.

I want to take your multi-tasking on-board air compressor one step further. I want to run the horns, air up tires, and operate rear suspension air bags on my tow vehicle. Since these three functions would not be used simultaneously, I think that a compressor sufficient to handle the biggest job would also handle the other two.

Is anyone out there doing anything like this?

Thanx, Brian

Yes, I have on-board air supplied by a converted A/C compressor. I use an old aluminum medical oxygen tank (3000psi) for storage. I run the system at 145 psi and have an air chuck in the engine compartment for air hoses and air tools. It is really nice to be able to air down the tires for rough road and then re-pressure them for the highway. I bought two old truck air horns on eBay and operate them with a 12V solenoid valve.

I've taken Cadillac horns off of various decade cars. The last was a 1980 Seville with [4] separate note horns buried in the tops of the fenders (accessible from under the hood). These were all the same size unlike the really cool 1960's models which featured a trumpet (also to be found on Buicks, etc, as an option).

Set it up with a relay-actuated harness off of the battery, looking for 13V+. Run the ground to the battery.

Install near a front opening as desired. Note location of original horns as a guide. GM horns tend to have a "sound-shaper" screw; sometimes individual horns lose their sweetness and are heard as either flat or sharp as they age, and as a result (for you) of their new acoustic chambering. Test each individually for voltage, for no loose vibrations (may need some work on mounts) and harmony with hood both open and closed (from a 25' distance in an open area).

I saw an old restored Mack truck in TN a couple of years ago in a truck stop, really sharp. Truck had a MASSIVE set of horns, turned out to be actual train horns. I asked the owner if he would toot em for us. After a moment of hesitation, he reached in the cab and by his seat was a hand operated valve, on what might have been 3/4" iron pipe looked like the old UP/DOWN valve you would see on an automotive lift in a gas station, one shot and it echoed off of the hills for what seemed like forever. MASSIVE.

Having a horn that gets attention when most everyone is on the phone, radio WAY UP etc, not a bad idea. I have a set of air horns (not installed yet) that run off of a mini compressor, I'll investigate some more along with some real back up lights, its all just 12V.

Train horns (Nathan Airchime and others) are illegal on private vehicles. Fun, yes. Responsible, no. Figure the total cost with installation at well above $1k for the real thing.
