Buying Guide: Key Considerations
- Brightness and coverage: Look for 360° viewing and high LED counts to maximize visibility in daylight and poor weather.
- Power and mounting: Consider 12V systems, magnet bases, or permanent mounts. Check cable length and mounting ease for your vehicle type.
- Weather resistance: IP67 or better and a rugged aluminum housing help ensure longevity in rain, snow, and dust.
- Patterns and control: A controller with multiple flash patterns, memory, and directional control improves versatility for different scenarios.
- Size and vehicle compatibility: Longer bars provide more visibility but may require roof reinforcement or extra mounting hardware.
- Maintenance and durability: Look for durable housings, scratch-resistant lenses, and long-lasting LEDs to minimize replacements.
