1. Brightness and Visibility
The primary purpose of warning lights is to alert others. Always choose lights with high lumen output and wide-angle visibility, ensuring they can be seen in daylight and adverse weather conditions.
2. Mounting Options
Different vehicles require different mounting solutions:
Surface-mounted for permanent installation.
Magnetic-mounted for temporary or portable use.
Grille and bumper-mounted for discreet integration.
3. Flashing Patterns
Modular LED lights often support multiple flash patterns. Consider models with programmable settings to match regulatory requirements or operational needs.
4. Durability and Weather Resistance
Look for IP65, IP67, or IP68-rated lights to ensure protection against dust, water, and extreme temperatures. This is especially important for outdoor or heavy-duty vehicles.
5. Power Consumption and Voltage Compatibility
Ensure the lights are compatible with your vehicle’s power system (typically 12V or 24V). Energy-efficient LEDs minimize strain on the vehicle’s battery.
6. Certifications and Compliance
Depending on your region, lights may need to comply with standards such as ECE R65, SAE J595, or NFPA. Verify certification to avoid legal issues.
