the 903X Series Beacon Warning Light – the signaling device designed to enhance safety and operational awareness across demanding industrial environments. Unlike traditional warning lights, the 903X series offers both advanced optical warnings and optional audible alerts, enabling clear, intuitive danger indication for vehicle operation, equipment failure, and other critical events.
Multi-Mode Visual Alerts – Choose from Flash, Rotation, Strobe, and Steady (constant on) light modes to suit different warning levels and applications.
Powerful Audible Warnings (Optional) – The with-alarm version delivers up to 105dB sound output (within 1m) with MP3 format support (8~320Kbps) and 10 preset warning tones.
16-Level Adjustable Volume – Fine-tune the alarm loudness to your specific environment without distortion.
Wide Voltage Compatibility – Operates on DC 9~30V, suitable for most vehicles, machinery, and industrial DC power systems.
IP65 Rugged Protection – Fully dust-tight and protected against low-pressure water jets, ideal for outdoor and harsh industrial conditions.
Low Power Consumption – Light-only version draws ≤130mA @ DC9V; with-alarm version ≤700mA @ DC9V, reducing electrical load.
Flexible Mounting Options – Standard fixing nut installation plus optional magnetic mount for temporary or drilling-free deployment.
High Visibility Colors – Available in Red, Orange, Green, and Blue lenses for color-coded warnings.
Wide Operating Temperature – Reliable performance from -20℃ to 70℃, suitable for extreme climates.
Fast Initialization – ≤1 second startup time for the audible version ensures immediate alert readiness.
