XRIDONSEN 37″ 104 LED Roof Top Bar

XRIDONSEN’s 37-inch bar combines 104 high-intensity LEDs with a spotlight TIR lens for broad, day-visible warning. Built in a waterproof aluminum housing, it’s designed for reliability in rain, fog, sandstorms, and snow, with an IP67 rating and a lifespan up to 50,000 hours. The digital display controller supports 26 flashing patterns, three directional quick-selects, and a customizable pattern, allowing operators to tailor signaling quickly from the cab or a rear position.
Buying Guide: Key Considerations For Emergency Light Bars
- Visibility and brightness: Look for a high number of LEDs, TIR or magnifying lenses, and 360° lighting to maximize roadside visibility during day and night.
- Mounting and installation: Consider magnets with robust suction cups or permanent mounting options. Check for compatibility with truck, plow, or construction vehicle roofs and the length of power cables (12–24V systems are common).
- Durability and weather resistance: An IP rating (IP67 or IP68) and a rugged aluminum housing indicate good weatherproofing for harsh conditions.
- Patterns and control: A controller with multiple patterns (26 or more) and memory recall helps adapt signaling to different scenarios. Evaluate whether a digital display or local switches meet your workflow needs.
- Maintenance and lifespan: Long LED lifespans (50,000 hours or more) reduce replacement costs and downtime in critical roles.
- Size and portability: Larger bars provide more LEDs and visibility but may affect aerodynamics and mounting options; smaller bars offer flexibility for compact vehicles.
- Compliance and compatibility: Ensure the bar’s flash patterns and colors align with local regulations and that the power system can support continuous operation without draining vehicle batteries.
