Reddit reviews Vixen Horns Loud Electric Motor Driven Horn/Alarm/Siren (Air Raid) Small/Compact Chrome 12V VXS-9060C

We’ve got Qs on all our trucks. My old volunteer EMS station has Qs on some of the ambulances. The guy who ordered the medics actually worked for for an emergency vehicle dealer and specked the sirens and horns like the fire departments.

Fun side note my wife needed a siren for a piece her band is doing (she’s a band director) so I ordered a little mini 12v siren.
When the concert is over I’m going to rig it up on a sit on fire truck for my son.

How about a black vinyl sticker the same size. Sure some (and you) would notice, but it is better than a black sticker or a botched touch up job.

Btw I'm a Electra cop glide rider and couldn't handle having the siren buttons without a siren. This guy was only $12, fits under the right side battery cover, and puts a smile on people's face.
