A Favorite...for Years!

• Drives any speaker
• Duplicates the wail of a police siren
• Kids love it!

Look out, here come the cops! Nope, only you and this siren kit. The SM-3 siren exactly duplicates the upward and downward wail of a police siren. Runs on 6 to12 VDC and is a loud 5 watts. Drives any speaker, but a horn type gives best results. Surprise your kids, or wife - if you live dangerously.
