Developed in 2012 by Zhejiang Liyi Safety Equipment, the 39000 Series Lightbar stands as a landmark in roof-mounted vehicle lighting. Most notably, it was our first model to secure the prestigious ECE R65 Class 1 and Class 2 dual certifications, marking a significant technical breakthrough in the R&D of warning signals. Since its launch, it has become a global favorite—particularly in Europe and the Americas—renowned for its exceptional balance of high performance and cost-effectiveness.
Versatile Design and Precision Fit
The 39000 Series strikes the perfect balance between a compact profile and broad compatibility. The lightbar body measures just 70mm in thickness, with a total height of 136mm (including brackets) and a fixed width of 300mm.
To meet the diverse installation requirements of various specialty vehicles, we utilize a modular light-box assembly design. This allows the 39000 Series to offer an extensive range of lengths, including:
350mm, 590mm, 690mm, 820mm, 1030mm, 1060mm, 1160mm, 1270mm, 1370mm,
1500mm, 1640mm, 1740mm, 1840mm, 1950mm, 2050mm, 2180mm, and 2220mm.
Whether for a compact utility vehicle or a heavy-duty engineering truck, there is a precision-fit specification available.
360° High-Intensity Warning Coverage
For maximum visibility, the internal light modules are arranged in a wrap-around layout, providing 360° horizontal coverage with zero blind spots. Depending on specific operational needs, users can customize light colors and utilize pre-set pulse flash patterns. This ensures that in complex environments, surrounding personnel and vehicles can immediately capture the warning signal, significantly enhancing safety.
High-Performance Core and Durability
Premium LED Technology: Equipped with energy-efficient, long-life LEDs that deliver consistent brightness with low power consumption.
Wide Voltage Range: Supports DC 9V–30V, making it compatible with the electrical systems of almost any specialty vehicle without the need for additional modification.
Industrial-Grade Materials: The outer shell is built to last. The lens is crafted from imported Japanese Mitsubishi Polycarbonate (PC), while the base utilizes high-strength ABS. Both materials are UV-stabilized to prevent aging, impact damage, or yellowing caused by prolonged sun exposure, ensuring reliability in the harshest outdoor conditions.
Integrated Audio-Visual Warning System
The 39000 Series is more than just a lightbar; it supports an integrated loudspeaker for synchronized sound and light warnings. The speaker is cleverly concealed within the mid-section of the lightbar and connects to a siren controller to output high-pressure sound levels (≤120dB). This powerful acoustic penetration extends the warning range, making it ideal for high-intensity work zones.
