- Dual Alert: Combines a high-visibility LED strobe with a loud piezo siren (typically 100dB–110dB at 1m) .
- Power Draw: Low current consumption, usually around 170mA at 12VDC for combined siren and strobe .
- Weatherproofing: Often designed with high-impact plastic or weather-resistant casing for indoor/outdoor use .
- Tamper Protection: Some models include a built-in tamper switch to prevent bypass or damage .
Vehicle Warning Strobe (e.g., DBG, Willpower)
- Voltage Range: Often operates on a wider 10–30V DC range to accommodate both 12V and 24V systems .
- Durability: Typically rated IP67 for waterproofing and built with aluminum housing or polycarbonate lenses .
- Flash Patterns: Many models offer multiple selectable flash patterns (e.g., 10+ modes) and synchronization capability with other units .
Simple Signal Strobe (e.g., ELK)
- Minimal Wiring: Frequently uses a simple 2-wire hookup for easy installation .
- Low Current: Draws around 210mA with a fixed flash rate (e.g., ~1 flash per second) .
