Hella012588061 Motorcycle Series Black 12V Disc Horn (Universal Fit-Single Blister Pack)

I have tried several sets of horns for my Triumph motorcycle that said no relay needed. They worked as I installed them but when I needed them only one honked and sounded like a sick goose. These horns worked perfectly without a relay and are much louder than the original single horn on my Triumph Trophy SE. I originally skipped these, going for the loudest claim without a relay and I should've started here.

These little horns are LOUD! Not for cars but great for motorcycle or four wheelers, etc. Great buy for the money

These are the dual disc horns kit. Came with the horns and mounting brackets. According to several reviews of these horns, they worked without a relay, so I was willing to give them a try. They mounted perfectly using the bolts for my engine guards, and since they're not polarity-sensitive, it was easy to wire them up. I ran a couple of "Y" wires off the OEM wires to both horns, then tucked the wires up so they're out of sight. Pleased with the sound output of these horns, much louder than the single Hella disc horn, which in turn was louder than the OEM single disc horn.

decently loud, definitely louder than stock, tone is higher pitched, but sounds ok. good bang for the buck so far

I installed these on an Evo Sportster. I wanted horns that were small enough to "hide" but still be loud enough. These little horns do the job. I mounted them low and tucked in between the frame downtubes. There is a mounting tab on the frame there in front of the engine crankcase and I installed them back to back on a single 2" long, 5/16" diameter bolt. Easy install and they blend in well.They are small horns that are 67mm or almost 2.75" in diameter. Each of the horns is tuned to a different pitch. Together they produce a bright, loud "European" tone. The sound is a bit obnoxious, but it will get noticed.I measured current draw and was a little over 3 amps for both at 12 volts. This means there should be no problem connecting them to most existing horn circuits. (No extra relay is needed)They say "water spray proof" and do have drain slots to get rid of any water. Time will tell how they last, but for the price, it seems hard to go wrong with them.

The metal mounting point snapped after only a few months. Probably fine for road-only motorcycles but definitely doesn't last for adventure bikes. Decent horn otherwise, not terribly loud though.

Really loud

Pure junk. Certified motorcycle mechanic couldn't get them to work properly.
