Customer Reviews

 90Deluxe Posted:

The first set I purchased stopped working within days. I returned them and was provided with a new set again they are not working. Stay away from Howards Horns

 bigtractor Posted:

I have had this horn for 2 years. It works sometimes. I had trouble with the wiring. The compressor fits nicely behind the old horn shield. It had air leaks at the back of the horns. The compressor doesn't seem to put out enough air. I am tired of it not working will buy a different brand.

 VRage Posted:

They look GREAT. But 2 things you must know before ordering. 1) The manufacture is sending these out untested with known possible defects and 2) if you call the manufacturer you will be talked down to like you are an idiot for not being able to fix the possible known defects in the item. Roll the dice if you wish. I did say they look GREAT.

 VRage Posted:

Look Bad A$$!! That is the only good thing I can say about this product. Does NOT go on easy like instructions say as the cow bell for the 2011 Wide Glide is too small. This was easily overcome. Wiring instructions ok if you know how to read a schematic and follow it which for me was easy. Once installed, got a weak tweet. So I double checked everything to ensure I had it installed properly and I did. So I called the company to be rudely talked down to saying I need to go to the company website and download the possible known problems with their suggested fixes. WHAT?!?! The manufacturer is shipping out a product with known problems?! So I spent more money getting the stuff needed to do all their recommended fixes to no avail. In fact it got worse, no tweet whatsoever. The only thing that can be heard to the compressor running. Called company 2d time to be talked down to AGAIN and told I have an air leak and to download their instructions again which I had already done. So I got some clear RTV and sealed the crap out of it. Still doesn't work. Two things to take away from this. 1) the company is sending out untested product with possible known manufacture defects and they expect YOU to fix them. 2) When you call them, they are less than professional assuming you screwed up by not fixing their manufacture defects. But hey, they do look BAD A$$ on the bike.

 jfwiv Posted:

They may look cool on your bike, but thats about it. I installed on a 2008 Softail Deluxe. Out of the box, the kit was incomplete. Needed 14 gauge wire, 3 female connectors, 1 male connector, 2 right-angle female connectors, 1 horn relay, and two hose clamps. Also needed electrical wire ties. The compressor does not fit neatly behind the stock horn cover. It sticks out below about 1 1/12 inches. Wiring diagram not included. You will need to go to the company website to obtain. You will need to route 3 wires from the back of the horn towards your battery. Once hooked up the horn sounded like a sick goose. Website instructions ( state I need to take the horns apart to adjust the sound - why arent they made with the fix if this is a problem? Going to buy teflon tape today and re-engage with the project. Very dissapointed with this product. I do not recommend.

Very loud, did what was needed

 dallen201 Posted:

Easy to install and looks great. The horn is piercing. I haven't had to use it yet but I'm sure when I do, I'll be heard.

 2005delux Posted:

Does not fit real well under the cow bell as described but you can make it work. The sound is not what I expected but it is loud which is what I was looking for. Installation instructions are so-so at best.

 Rogernii Posted:

To install was quick and easy. It does hang out a bit farther than the stock horn. So you have to change your leg position a bit. I only had to use it once and it worked great and I should of purchased it sooner.

 fcsallan Posted:

Unbelievably loud for an instant on compressor with no reserve tank. Follow the instructions for wiring and you will be more than pleased.

 aaronmorgan Posted:

Very loud. High quality. The sound was higher pitched than I anticipated though.

 cbinet123 Posted:

To me it is the the most convenient set of air horn for my bike.

 Garjammer Posted:

Went on easy and worked very well,,,ok LOUD

 pappys49 Posted:

Work great but install of the cow bell with adapter bracket does not want to stay still, keeps twisting out of place.

 130chief Posted:

Loud and sharp looking

 bsb2 Posted:

Nice and loud, but after a couple of years,the chrome finish flaked off from parts of the horn. Flaking chrome looks bad.

 ScottsAwsome1300VTX Posted:

This is a GREAT product! This does require some basic level of electronics background to understand the installation of the relay with the schematic provided.

 brayshawlm Posted:

Mounting the horns was a nightmare at best. This product states everything is included and would be easy. NOT! When i finally got the horns installed it let out a wimpy TooT too which my friends in the garage and my family in the house broke out laughing hysterically. Oh the comments the filled the air like (Hey don't fret, they look like great fly catchers...How sweeeet!... 1. You open the box and read that you need extra heavy electric cables to hook directly from the compressor to the battery. Ah yes where is the heavy duty wire? They don't come with the kit however the instructions do show you where you can buy some. 2. Then it says use the relay in this kit? Ah i guess I need to order a bike manual to know which and where to locate the original relay that needs to be swapped out. 3. I have a FLHR road king and when I mounted the main bracket the choke cable was to short to slip it on. Major jerry rigging, I ended up mounting the bracket onto the back of the hole bracket which now the horns are prev

This review encompasses two things. Howards Horns are now on my 1999 Road King and work flawlessly and look great. I find them to be everything they were advertised to be. Initially I had received them as a gift for Christmas. The original pair broke at the mounting bracket. J&P took them back without any hassles whatsoever and no shipping costs to me. They promptly sent replacements again without shipping costs. To my way of thinking this is what customer service is all about. Thanks J&P for great products and great customer service.

 wireday Posted:

The horns work fantastic! Follow the installation instructions on line and blowup the pics of the horn mounting instructions and you shouldn't have any problems. The horns have already saved my bacon twice from cages not checking before changing lanes.

 hwmordell Posted:

They are good and loud. When I tested them my neighbor thought that an alarm had gone off. The chrome and the hardware seems to be of good quality. My only complaint would be that the wiring that was needed wasn't included in the box.

 motorcyclesforever Posted:

We love our new horn and it is loud. Have had lots of comments on how good it looks on our Heirtage Softtail.

 klinefinancial Posted:

These are nice and loud and they look first set had one of the horns fall off on the freeway. I put on a second set and after a month only one horn works. The cow bell cover has fallen off and broken 3 times. The stress of the weight mounted here does not work well. I give up and am going back to stock horns (also they vibrate a lot at low speeds). I wish they worked better and I really tried but they are NO GOOD.

 jflipb Posted:

Love the horn! However, installation isn't quite as easy they make it sound. I installed the horn on a 2005 Road King Classic and would like to point out the following so other people can benefit before they install: 1. The rubber mount behind the stock horn has two bolt studs joined together by a round piece of black rubber with thin metal washers at each side. Make sure you twist the metal washer IN THE BACK with your vice grips or you could shear the rubber piece in half rendering the part useless (and it's reused later in the install) 2. When my Road King was turned off and the switch was in the accessory position, blowing the air horn caused the fuse to burn out. This can be overcome by installing a 20amp fuse instead of the factory standard 15amp in the accesory position in the fuse box (my local H-D dealership says this is not detrimental to anything else running on that circuit, and after 1 week; so far so good). Like I said, love the horn, but it would have been nice to know this information beforehand, hence the review. PS: J&P doesn't carry the horn covers for the dual horn (as of this writing), but you can go directly to Howard's web site and order them for $20 plus shipping.

 richv2710 Posted:

Ordered for my '05 Road King. Part arrived in record time, nicely packaged to protect the gleaming chrome. Bolted right up with easy instruction(s). Had tried out the product while in Sturgis last summer; should've bought them then. Totally satisfied. Thanks.

 rapido125 Posted:

Great horns in their sound and intensity. I've had mine for about 6 mths now and they sound awesome. Like a freight train coming at you. Talk about waking up a cager with the cell phone up his @#$! The install kit (being rather generic) lacks all of the things you will need to complete the job. And the mounting bracket had to be modified to even begin to fit on my FLHRCI. The main thing is to keep watch on those fuel lines after you put it on. My 2000 Road King Classic didn't appear to be anywhere near rubbing fuel lines. But lo and behold, after about 12000 miles I get gasoline spraying me in the face at 75 mph going down the road. Yeah, I should be inspecting the scoot better. Yeah, I shouldn't be riding 75 in a 65. Yeah, you better keep a FEEL on those fuel lines around anything you add to the old putt. just my experience.
