Hi. I picked up 2 large air horns today from the local junkyard, and am stumped as to where they will go. Each trumpet is approximately 2 feet in length, and I do not have my compressor yet. I drive a full-size 1988 Bronco. My questions to you readers are: 1)Where can I fit them!? Are there any hiding places that I can mount the two horns?.......2)What size compressor will I need for so large horns? Will a standard air horn compressor (air pump) work for these horns? I appreciate your answers, as well as ANY installation help or tips or any related pointers. Thank you...

Wow Dude! you da man!...i've seen them mounted on top of the cab..awesome!

hella makes a complete kit..but their compressor may be too small for your 2 footers...

here is a site for large air horn compressors...

and

Grover duals too and the comp is 250.

maybe you can get it from an old truck?

here is a good hella air horn installation page for you anyway:

good luck!

hey! every think about using aircraft landing lights? i am

 

Thank you for your input. I still have one question,though- what hardware is needed for these horns? (Keep in mind that they are from a ten wheeler) I constantly hear the term "air compressor", but I do not know how to rig it. Would a simple air storage tank (say, for a nail gun) work? Or do I need some sort of compressor that forces air through? Also, what types of hoses and other parts are needed to make these operate? As you can tell, I have no experience with air horns, and am looking for help. Assuming I mount the horns on the roof, how do I hook both horns to a single pump/tank? Do I need two tanks? Any readers who know anything to help me, please share that knowledge. Thank you.

AIM......where did you find aircraft landing lights? i'm looking for them myself.

I've mounted 2 pairs of air horns on my own Bronco, and still have to finish the project. To do all this, you'll need an air compressor (a stock York air compressor from a Bronco a/c is perfect), a storage tank of some sort(mine's a 20gl air tank for other uses), one main air line to the lanyard, and two air lines - one for each horn. I can very easily draw up an easy schematic for you if you'd like. In fact, by the time you read this, I'll have one drawn up, so if you want, I can email it to you, or maybe even attach it here

Just lemme know,
David

 

I just posted a diagram in my Photo Point site - http://albums.photopoint.com/j/View?u=815167&a=5925321&p=36155601&Sequence=0&res= high

Dear David,
First off, you have been a tremendous help to me. No one else even lifted a finger to do so little as tell me they didn't know, but you- you went far beyond what was expected and even sent me an installation diagram. Thank you so much. Okay, back to the questions. The air conditioning in my Bronco does not work (there is a leak in a few of the lines, and the tank is now empty. I dont plan on fixing the A/C anytime soon (in fact, it will probably leave my possession without any air conditioning). That means that I can use the compressor for my horns as you suggested. Where do you suggest mounting the compressor- under the hood? Or inside the cab somewhere? And the lines that connect the compressor to the tank- are those just regular air hoses, or are they an insulated/pipelike material?.(I have your diagram in front of me now). You show that I should have a mini air gauge mounted in the dash. That means that the compressor is most likely under the hood, and that I'll have to make room for the gauge somehow (probably in the small change inlet beside the steering wheel- about the size of the ashtray). How do I attach the air gauge to the air hose? Does it slide through or something of that nature? I assume it does. From there, the line enters the air tank, which you show as having a pressure switch. Is that something I add myself, or does it come with the tank? You also show a 3-way regulator off of the back of the tank. What exactly does this do? You also show a toggle switch, but is that fixed to the tank? The switch itself is used to turn the compressor on and off, correct? Or does the compressor have an automatic shut-off at a certain psi? I understand the rest of the diagram (up to the lanyard valve and from there to the horns/chain.) What I'd like to know is- how did you mount the horns to the roof? Did you use a pad of some kind between the horn base and the roof? Would you recommend covering the opening of the horn (in my case, the circle opening- some are rectangle) to protect the horn's insides from weather and debris? I see the big trucks with covers on most of their's (they usually say Mack), but doesn't that severely muffle the sound? I know I've bombarded you with questions, but I have nowhere else to turn to. Thank you in advance if you choose to reply.

gee..no one else tried?..shucks.....
and.....

redhorse...i bought the landing lights from mil surplus at at a Nvay air base in Pennsy...14 volts babies..lol
I'll get the numbers for you....others sell them surplus and new on the www...

Man, so many ?s...lol OK, one at a time: first of all, if your truck has a/c now, leave the air compressor right where it is....it needs to be run off your belts. The air lines I used are rigid copper tubing 1/2" dia. with the appropriate elbows all soldered into place and held with pipe clamps that use one screw to hold it all down. You don't HAVE to have an in-dash pressure guage, I just put that there for my own benefit, cause I'm going to install one. To do it, yeah, finding a place for it is the first thing. And you can use either 1/8" flexible copper tubing(which I probly will) or 1/8" plastic tubing(made for high pressure) The air pressure switch will most likely be something you'll be adding yourself - UNLESS you happen to find an old air compressor that framers use. I actually had two broken job-site air compressors I got to take the parts off of. The air regulator I put in my diagram is also for my benefit - I'll be running air tools from that air tank. The toggle switch is the main power switch.....I turn it on when I need air, and when the tank gets up to pressure, the pressure switch will shut off the compressor. Then once I'm done, I just turn it all off with the toggle switch. I mounted my horns at the back of the cab, where it has a small rise, before it gets to the removable top - more room for the air fittings in there for me. As for the covers, I'm not gonna bother....if I get ##### in there, I'll just take off each horn, clean it out, and put it back together. but no, the horn covers won't baffle the sound as bad as you might think. As long as there's a way for the sound to travel, your horns will still be ear-splitting loud.

Anything else, just ask bud, I know what it's like not to get the answers you're looking for
