150DB Air Horn, Super Loud Train Horn for Truck Boats Car

The build quality is great - way better than I expected for the price. The horn is made of metal and feels sturdy, and comes with some easy mounting points. The air pump for it is also good and generates the air flow needed for the horn without any issues. I don't have a sound meter so I don't know how loud it actually is, but it sure surprised me when I powered it up for the first time. I was skeptical of the 150 dB claim, but I'm fairly certain that it actually reaches that if you were to measure right at the end of the horn. At any rate, it's easily loud enough for whatever you're planning to do with it. The sound of it is also great (see video). The 680 Hz specification had me somewhat afraid it'd be an annoying high-pitched sound, but it absolutely is not. I only wish they'd have included a relay - the air pump draws close to 20 amps at 12V, so it'll ruin any switch you connect to it pretty quickly. If you're able to work around that, I can only recommend this horn.

The RUPSE 150 dB Air Horn delivers an impressively loud and attention‑grabbing sound — perfect for cars, trucks, or boats when you need to be heard. Easy to install with a 12 V setup, it feels solidly built and reliable. If you want a horn that really stands out and boosts safety on the road or water, this does the job with plenty of volume. Highly recommended!

Easy to fit and absolutely awesome sounding horn. This must have came off the 12:25 train from Glasgow to London. Do not buy if you want a subtle sounding horn. This is a beast and will definitely get everyone's attention 😂

They were easy to install and when tested they were very loud. I had to extend the power cable as it wasn't long enough to reach the battery. I boughtva second set for another car and there was no wiring instructions. For anyone wanting to wire these in here's the wiring colours Red 12v+ to battery Yellow to back of air horns Blue is a negative White to car current horns + wire. If your car uses the chassis as a negative you will need to run a negative from the air horns also. I just simply joined an extra negative wire and the blue wire to a mount point on the chassis.

For the money it’s ’ok, you get what you pay for - it’s not bad value for money. It’s a hard plastic and not cheap plastic but looks to be chrome spray finished. The fitting was quite easy to mount to where I wanted it to go. What would have been easier for non electrical minded people is wiring instructions as it comes with a bit of wiring and a relay. There is no manual or wiring instructions with it at all - nothing to tell you what colour wires are what . Not sure on rust resistance as it’s on my boat. So when it gets covered in sea salt that’s when the true test will show! As for the loudness.. yes it’s loud for sure, deafening if you were next to it I’d say. Check out my video of it. All in all, for what it cost, I’ll see how long it lasts - tried adding a video but comes up with an error. Will be a video on my YouTube channel of it - Skint Boater

Brilliant LOUD Horn . Easy fit .

i orderd the double horn. absolutely horrendous, it makes a high pitch toot sound rather than a low pitch horn. thsnt powerful enough for the double horn and the instructions are useless. they tell you thr wrong way to wire it which could end badly if you dont understand the correct way to do things (lots of sparks if you follow te instructions). unfortunately im past my refuld period but DO NOT buy the double one.

It’s loud ! And the tone is spot on , deep and loud - just what was needed. This is a bare kit , what I wanted as I hooked mine up to a auxbeam control panel. If going to use a switch you will need a momentary type switch, relay, fuse according to what method you take supply from and cable and an hour on YouTube on simple relay wiring ….. It is definitely worth it

Produit de qualité, couleur et matière du produit super. Un son de qualité..

Compresseur à démonter et graisser pour éviter de gripper. Klaxon au son de " camion " , comme prévu, moins puissant qu'un Klaxon sur bouteilles d'air comprimé, mais ça fait le job.

Cette trompe est incroyable ! Petit bémol, pas de câbles fournis avec… Il faut s’y connaître un peu pour l’installation !

L'effet non conventionnelle permet de réveiller les chauffards endormis au volant

Super klaxonne son très puissant équivalent à un camion ou un bus
