GAMPRO 12V 150db Air Horn, Chrome Zinc Dual Trumpet Air Horn with Compressor for Any 12V Vehicles Trucks Lorrys Trains Boats Cars Vans (silver)

This was excellent at first but its only been on the car a couple of weeks and already the large trumpet has stopped working, it sounds pretty lame with just the small one and I really cant be bothered to strip it out of the car. Their is zero chance of water ingress into the trumpets, I have them firing directly down. Sometimes the big one comes on but mostly not. The compressor is mounted very close and the tube is very short. Edit: I cant fault this company, they replaced the horn and its now perfect, I will also say I did not have to extend any cables, everything that was needed was included, I highly recommend this product, it sounds fantastic and very loud.

These horns sound great, made me laugh the first time I heard them. Pity that a bit more care wasn't taken in the packing of them.The air pump motor ( quite heavy in relation to horns) was sandwiched inbetween and on top of the metal horns. The photo shows the damage caused by this action. Also the motor had obviously been dropped onto a hard floor prior to packaging, as it to shows signs of damage. It's packaging was unscathed. As the horns are not going to be on show and the pump works, not to bothered about it. But it was a shame a little more care wasn't taken in the packing of this product. Still great sound...... Edit.....problem solved by Elle at Gampro....many thanks..new horn...still smiling

Exceeded my expectations on the physical use of it. However the installation process was such a pain. The positive wire is good because it’s so long, but the negative wire must be 15cm tops, then the wire to horn (blue) is again the same length. So it’s very hard to find a good spot to put it. In the end I just stripped some old wire and wired it myself, this works really well. 4/5 because of short wires.

this thing is LOUD!!! have got a few peoples attention on the road when required. fantastic and glad i found it. very easy to fit, however the included relay is a bit rubbish, it failed after a few days with obvious water ingress, replaced with a standard 12v 40a relay.

Ok but not very loud.. the pump is week

Not fitted yet so have not heard them. However, have opened the box and seems good quality, with good electrical fittings. Only time will tell.

Used in my be camper the old horn wasn’t very good now sounds great

Good quality and a relatively easy fit on my classic car. Wiring was not long enough but was easily extended. One damaged bolt and slightly obscure instructions cost one star. A great sound though!

I bought this product to replace my stockhorn in a Nissan Versa, definitely pumps out good volume however with the instant compressor that is supplied it doesn't even come close to the 150 decibels but it is still much louder than my stock horn, the only way you're going to be able to get close to a hundred 50 decibels is to install a air reserve tank and push up the PSI. Just giving you a heads up If you own a big truck like an F250 or bigger then most likely your stockhorn will be the same volume as this product

Economico potente e costruito bene

I purchased these to replace a pair of 3 yr old units from Princess Auto. The pump on my old unit had seized.... So, I fitted these puppies and am well impressed. The horn assy is well built, and the pump is the same as I have seen on many previous units I have used over the years... I admit I was a little cautions given some previous reviews for this unit, but so far I have not been disappointed. They sound awesome, just like the youtube review I found while researching them.... (yes, I do look stuff up quite a lot...) They look really nice mounted behind the grill of my 2010 Ford Ranger, and sound nice and loud!! Perfect for getting people to realize you are there when they are off on their phones while driving.... I would recommend this product to anyone who wants a simple install and great results..

It came with everything except the battery. Louder than expected, Totally satisfied as I have ran them at 70 p.s.i., still working.

Klaxon simple rapide et efficace Je recommande
