HellaH31000001 Sharptone 12V High Tone/Low Tone Twin Horn Kit with Yellow Protective Grill, Includes Relay, 2 Horns

Great horns but the packaging needs to actually protect them.

Sound quality is terrible and not consistent. Not sure how people are rating these horns positively! Limp and diluted. Sound like you got two different cheap horns from two different manufacturers. Maybe using either one by themselves might be ok, but together, they are completely out of harmonic balance.

Just Great well worth the money - just check you have OE not counterfeit goods - hologram

After only a matter of months with these being fitted the paint is flaking off and going rustyWaste of money - not simple to contact seller either!!

No louder than original horns

These horns, made by Hella, are a great update without going overboard. They are loud but not obnoxious. They install easily and look good as well. They fit in most stock locations.

There are no dimensions on the listing for this horn.The listing says it'll work for a motorcycle, but at 5" in diameter it way to big for any motorcycles that I know of. The standard size for motorcycles is 3".I'm sure it could be a great horn for anything that can accommodate a 5" diameter horn.

Poor sound quality i give this product in one month before in many time in repair very poor bad product

Pas super évident à installer quand comme moi on n'y connait que très très peu en électricité. Montés sur une 350z, j'ai l'impression que le niveau sonore est seulement un peu plus élevé que les trompettes d'origine (malgré l'installation du relais).Elles respirent cependant la qualité et sont assez esthétiques !

Great units, only slightly larger than my OEMs so no issues with fitting them in the current mounts. HELLA also provide a relay for those who need one of this size (already had one OEM so it's a spare for the bits box).I needed to run an extra earth cable which gave me chance to clean up some wiring (oem were denso which only have a positive).Overall lovely product, nice secure packaging and performs well. Have noticed that even though people can't see me, they pay attention to the horn frequencies alot more.
