The 100W compact siren system delivers strong audible output with 118-124dB, designed for vehicles where space is at a premium. It supports multiple operation modes including horn, radio, and siren with documented Yelp, Wail, and Hi-Lo tones, plus manual horn and manual siren options. The setup is complemented by two 16A auxiliary switches to power external devices, expanding the vehicle’s supervision capabilities without adding clutter.
Key considerations
Compact form factor and reliable performance are ideal for smaller trucks or fleets needing a discreet but effective warning system. The two on-board switches provide convenient integration for additional lights or accessories, while the horn and siren options give operators flexibility in different traffic scenarios.
SoundAlert 12V 100W Siren Kit – 2 x 16A Aux Switch
This version reinforces authority with a 100W amplifier and advanced tone suite, including Wail and Hi-Lo. The two 16A auxiliary switches extend the system’s reach, enabling power to external devices. A horn override feature lets drivers trigger the air horn via the stock horn button, ensuring continued road focus during urgent operations. This configuration is well-suited for fleets needing robust control without adding complexity.
Key considerations
Two aux switches enable expanded control for strobe lights or auxiliary equipment. Horn override enhances situational safety by keeping hands on the wheel while engaging emergency audio cues. It’s a good balance of power and user-friendly controls for mid-sized trucks.

The two 16A switches provide auxiliary power options, supporting additional lights or devices needed during operations, such as scene lighting or external alarms.
Key considerations
Higher dB ratings translate to better visibility in noisy environments. The integrated radio rebroadcast feature helps deliver synchronized messages, which can be crucial for coordinating with other responders. Suitable for larger vehicles that require louder, more audible warning across urban and rural settings.

Buying Guide: Key Purchase Considerations
- Power and reach: Higher wattage equals louder output and longer-range audibility, especially important in urban environments or noisy highways. Choose a unit that matches vehicle size and desired coverage area.
- Tone variety and control: Look for multiple siren tones (yelp, wail, hi-lo) and horn options for different scenarios. Features like radio rebroadcast and horn override can improve message clarity and safety.
- Auxiliary power and expandability: Two or more 16A switches allow powering lights or other devices. This can reduce wiring complexity and simplify installation in trucks with multiple accessories.
- Installation footprint: Slim or compact speakers save space on smaller trucks, while larger vehicles can accommodate bulkier systems with heavy speakers. Consider mounting options and weather resistance if used outdoors.
- Interoperability: Systems with PTT mics, remote controls, and Bluetooth inputs work well in fleets needing hands-free operation or mobile messaging from smartphones or tablets.
- Reliability and support: Choose brands with proven track records in emergency or commercial vehicle use. Check warranty terms and availability of replacement parts or accessories.
- Regulatory compliance: Ensure the selected tones and loudness meet local regulations for emergency signaling to avoid compliance issues in specific jurisdictions.
- Cost of ownership: Consider not only the initial price but also the longevity of components, ease of installation, and potential need for professional wiring in some trucks.
Across these options, fleet operators can balance compact design with strong performance, selecting a kit that aligns with vehicle size, mission requirements, and installation capabilities. By considering tone versatility, auxiliary power, and ease of use, drivers can maintain clear communication and safety on the road without compromising vehicle operation.
