CJ-403MPD-ZL 400mm LED Full-ball Traffic Signal Light with Dual 8-Second Yellow Countdown (Aluminum Housing, Glass Lens, IP53)

• Large-Format Full-Screen Display
Featuring a 400mm luminous diameter, this signal provides full-surface red and green coverage paired with a dual 8-segment yellow countdown timer. This allows drivers to anticipate signal changes in advance, ensuring rapid and safe recognition of traffic commands even in heavy rain, thick fog, or complex roadway lighting environments.

• Weather-Resistant Aluminum Housing
The chassis is constructed from high-strength aluminum, offering superior corrosion resistance and structural integrity. The glass lens is engineered for high impact resistance and anti-aging performance, guaranteeing the long-term stability and reliability of the signal during continuous outdoor exposure.

• Wide Voltage Adaptability
Supporting an input range of 85~264VAC, the system seamlessly adapts to power grid fluctuations across various countries and regions. This ensures the traffic signal operates consistently and stably under diverse electrical infrastructure conditions.

• Low Power Consumption & High Efficiency
With a rated power consumption of ≤8W, the unit utilizes high-brightness LED light sources characterized by low heat generation. This energy-efficient design extends the operational lifespan of the hardware while reducing electricity costs and maintenance overhead.

• Excellent Protective Performance
Achieving an IP53 protection rating, the enclosure is effectively sealed against dust accumulation and rainwater splashes. It is purpose-built for long-term outdoor reliability, ensuring the signal remains stable in challenging weather.

Lightweight & Streamlined Installation

Dimensions: 1460×503×130mm

Net Weight: Approximately 15KG

Packaging Size: 1530×570×235mm
The rationalized, compact structural layout facilitates efficient logistics, rapid on-site installation, and simplified routine maintenance, making it an ideal choice for urban arterial roads and major intersections.

Installation & Compatibility
Stable Structural Design: The lamp body is approximately 1460mm long and weighs about 15kg. The aluminum alloy housing provides high-strength support. It is recommended to use double-point brackets or reinforced U-bolts for installation on traffic poles to ensure long-term stability.

Dual Countdown Control: Features a built-in dual 8-second yellow light countdown function that operates in synchronization with the red and green lights, alerting vehicles and pedestrians of upcoming signal changes to enhance traffic safety.

Modular Maintenance Convenience: The luminous modules, countdown components, and drive power supply can be disassembled independently, supporting rapid replacement and maintenance while reducing the workload of disassembling the entire unit.

Weatherproof Protection Design: The aluminum alloy body paired with a glass lens and an IP53 protection rating effectively prevents dust and water, adapting to complex outdoor environments such as urban arterials, overpasses, and tunnels.

Applications
Urban Intersections & Arterial Roads: Used for omnidirectional signal control combined with dual countdown alerts to improve the ability of drivers and pedestrians to anticipate signal changes.

Highway Entrances & Ramps: In rapid traffic diversion scenarios, the dual countdown function prompts deceleration and preparation for stopping, improving traffic safety.

Large Intersections in Industrial Parks: Provides omnidirectional signals and countdown displays for internal park roads and logistics channels to optimize vehicle scheduling.

Bridges, Tunnels & Underpasses: In environments with limited visibility distance, the dual countdown function ensures drivers are promptly informed of the remaining transit time, reducing traffic conflicts.
