Reviews of FIAMM horn

I installed a set of Fiamm Highway Blaster horns once. To make them loud you need to install the optional sub wiring harness with a relay. This steps up the power and your motorcycle will sound like an American car from the 1970s.

I swapped mine with a “FIAMM 72112 Freeway Blaster LOW Note Horn” just because I didn’t care for the stock tone. Cost was under $20 and took 5 minutes

Use the included relay to power them, the stock wires won't cut it. Use the stock connection to power the relay. You won't regret it. I've put these on every bike I've owned since 1984.

In installed these FIAMM 74100 horns on my son's 337. They are less that $20 on Amazon and work great. You need to make a jumper wire to go from the connector to the horn, but only for the +12v connector since the mounting bolt provides grounding.

Fiamm Freeway Blaster Horn #3830. This horn generates a shattering 132 decibels and will likely get just about anybody’s attention. I had two of these horns on my old '79 street Rabbit.

i put in a FIAMM from a 90s saab 9000 and its way loud now.
