Packaging was secure. Horn was easy to install and worked perfectly.I like that the sound level is adjustable. Price was great-- much cheaper than anywhere elseI looked. Highly recommend it. I put this on a golf cart-- perfect!! ### ⭐ 1.0 out of 5 stars Works but....... *by J***N on Reviewed in the United States on June 3, 2014* Maybe I didn't install it correctly but depending on how tight you put the middle screw is the tone it has. Probably not suppose to be like this but it is. It sounds low and flat. I completed a msf course the other day and they had great loud sounding horns. Wish mine was like that. I guess you get what you pay for. It will make it so you pass inspection. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Not great, at least for me. *by M***7 on Reviewed in the United States on April 27, 2015* OK, so these are really cheap honestly there hard to knock on just because they are so cheap. To be honest though no matter how cheap they are they are almost a waist of moneyNote my pros and cons listProThere nice and smallThere decently loud, although for me they are a deafening high pitch. But hey there to make you heard not to sound pretty.They are fairly atractiveEasy to install, same fittings as my bike.ConsOK to preface this. I have been trying to get my bike ready for its July inspection required in PA since I got my bike in February. These horns are the last piece of the puzzle, my old ones were big ugly and non working. I assumed my old ones died when I took them apart (you could do that with things built back in the good old days) my assumption was right.Being as this was the last piece of the puzzle to get my 1983 Honda nighthawk back to utter perfection I was so excited when they arrived in the mail! The brackets that come with it don't match my bike and aren't necessary for me since the necessary brackets are already on my bike, in other words all I should have had to do I theory is uninstall the old horns via the bolt in the back and reinstall the new ones the same way the old ones came off. Well I removed the brackets from the back of the new horns and attached them to the brackets on my bike, connected wires, should be good to go right? Haha nope not even close! There are two adjustments on these horns too I guess get the desired tone and pitch you wish the horns to make. The one adjustment is the center screw that bolts on to your bike it's adjustable with a flat head screw driver. The problem comes when you bolt it on your bike, it is impossible not to twist the screw in while bolting it on your bike there by muting it! What comes next is what seems a never ending game to adjust both screws while trying to bolt it to your bike, belive me hours and hours of trial and error. At the end of the day they both work, but this is far from a simple slip on part not even close.So I suggest you learn from me, get the horn with the black bracket, the bracket on this one is an ugly peacock color cheap metal. Removing it will be a nightmare at the end of the day because the included bracket is attached the perfect way so the center screw doesn't mute the horn.So consThis is a big one!You can not remove the included bracket and just your own, doing so as I did will result in hours yes hours of tweaking just to get these horns to work.At the end of the day, yeah there alright. Just wish I would have known what I know now haha!4 stars because they worked once adjusted just right, but minus a star for that center screw not being welded fast. There is no reason for it to move. But then again maybe I'm wrong I'm clearly not a horn specialist. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/10804415-horn-12v-2-terminal-2-5](https://www.desertcart.pl/products/10804415-horn-12v-2-terminal-2-5) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
