400mm Traffic Signal Red and Green Lights
The 400mm Traffic Signal (red and green lights) consists of two units: a red unit and a green unit. Widely used at intersections and other locations, it is designed to guide the movement of pedestrians and vehicles, effectively managing traffic flow to ensure safety and order. Featuring high-brightness LEDs, the lights offer striking, distinct colors and are highly visible from a distance, ensuring excellent visibility both day and night. By switching between different colors, this road infrastructure conveys instructions such as “proceed,” “stop,” and “caution” to road users. Its primary functions include scientifically allocating right-of-way, regulating the flow of vehicles and pedestrians, improving traffic efficiency, and reducing traffic accidents at intersections.

400MM traffic light two aspect
Red Light Warning · High Penetration
High-brightness LED chip with strong light penetration – ideal for high-visibility warning scenarios such as no-entry signs or equipment malfunction alerts, offering exceptional long-distance visibility.
Green light – More friendly
The soft yet clear lighting is specifically designed for traffic signal control and monitoring the normal operating status of equipment. 400MM traffic light two aspect offers a visually friendly design with high recognizability, ensuring safe traffic flow guidance.
product function
Traffic Signal Function
Red light (No Entry): When illuminated, 400MM traffic light two aspect indicates that vehicles or equipment are prohibited from entering the lane; this serves to intercept and restrict traffic flow.
Green light (Authorized passage): When illuminated, 400MM traffic light two aspect indicates that vehicles are permitted to enter or proceed through this lane normally.
Long-distance outdoor visual inindication
400 mm illuminated surface with high-brightness LEDs; maximum visible range exceeds 300 meters – ensuring clear visibility even under strong light, backlighting, or rainy/misty conditions; ideal for long-distance observation scenarios such as highways, main roads, and tunnels.
The sun-shading brim (the red and green outer circles in the diagram) reduces glare caused by direct sunlight, preventing misinterpretation of the traffic light's on/off status during the day.
All-weather stable illumination
Operates on a wide voltage range of 85–265 V AC, suitable for extreme temperature environments ranging from –40°C to 80°C; features IP53 dust-and splash-proof rating, enabling long-term stable operation both indoors and outdoors even in harsh weather conditions.
Flexible installation and adaptation
Supports both horizontal and vertical installation methods; when paired with an L-shaped bracket, 400MM traffic light two aspect can be quickly secured to structural members, making 400MM traffic light two aspect suitable for a variety of installation scenarios.
Simple power-on control
Simply connect the neutral and live wires to turn 400MM traffic light two aspect on; it supports external switches or controllers for on/off control and can be seamlessly integrated with any complete signaling system, offering simple and convenient operation.
Engineering Application Scenarios and Supporting Functions
Lane Control (tunnels, toll stations, elevated ramps): Replaces the red cross and green arrow signs to indicate lane opening or closing; red light = lane closed; green light = lane open.
Solves core pain points for customers
• Solution: With only red and green dual lighting, the unnecessary yellow light unit has been removed, resulting in lower equipment procurement costs and a more compact device size – making 400MM traffic light two aspect perfectly suited for scenarios where pole-mounted installation space is limited.
• Solution: 400 mm large-lighting-area LED lamp disc with built-in sunshade to reduce glare; high-brightness LEDs ensure long-range visibility and clear signal recognition even in rainy or foggy conditions, thereby reducing the risk of driver misjudgment.
• Solution: IP65 protection rating – dust-and water-resistant; wide operating temperature range – resistant to direct sunlight, rain, and snow – enables long-term stable operation in outdoor environments, reducing equipment downtime due to malfunctions.
• Solution: LED light sources feature a long service life and low power consumption, helping to reduce electricity costs; the modular lamp panel allows individual lamps to be replaced when faulty, eliminating the need to disassemble the entire fixture, thereby lowering spare parts procurement and high-altitude maintenance costs.
• Solution: Direct integration with traffic signal controllers and turnstile control systems is supported; the nighttime flashing warning mode eliminates the need for additional warning light equipment, simplifying control system configuration.
• Solution: Dual-unit design reduces the overall machine height, minimizes installation space requirements, and makes 400MM traffic light two aspect ideal for installation in confined spaces.
• Solution: A red light indicates that the lane is closed and vehicles are prohibited from entering; a green light indicates that the lane is open for traffic. This provides drivers with an intuitive indication of the lane status, preventing vehicles from mistakenly entering closed lanes and reducing the risk of traffic accidents.
