Model 400 Dual-8 Countdown Traffic Light
Introduction to the Model 400 Dual-8 Countdown Traffic Light:
Timers are a vital component of traffic management. A countdown display—also known as a remaining time display—is a device that operates independently of traffic signals but synchronizes with them to show the remaining time for each signal phase. It alerts vehicles and pedestrians to prepare in advance to proceed or stop, thereby promoting smooth traffic flow at intersections and enabling vehicles and pedestrians to pass through quickly and safely. It plays a crucial role in maintaining good traffic order and reducing the incidence of traffic accidents.
Based on their operating modes, they can be classified into learning-type countdown displays and communication-type countdown displays. The Dual-8 Countdown Single Light consists of a single unit with a plastic housing.
It features high-brightness LED bulbs with striking, distinct colors and a long viewing distance, ensuring excellent visibility both during the day and at night.

400MM Dual 8 Traffic Light
Red Light Warning Countdown
High-brightness LED chip with strong light penetration – ideal for high-visibility warning scenarios such as no-entry signs or equipment fault alerts, offering exceptional long-distance visibility.
Green Light Countdown
The soft yet clear lighting is specifically designed for traffic signal control and monitoring the normal operating status of equipment. It is visually friendly, highly recognizable, and ensures safe traffic flow.
Product Features
Reduce intersection accidents: By providing drivers with advance information about the remaining time at traffic signals, this approach helps minimize sudden braking, running yellow lights, or running red lights, thereby reducing rear-end collisions and tail-gating incidents at intersections.
Enhance traffic flow efficiency: Vehicles can anticipate start-stop signals in advance, decelerate in an orderly manner at the end of a green light phase, and prepare to accelerate in advance at the end of a red light phase, thereby increasing the throughput at intersections.
Auxiliary traffic management: Designed for large intersections (400 mm wide field of view, suitable for main roads and crossroads), featuring long-distance recognition to facilitate large vehicles or distant vehicles in reading time information.
Visual long-distance warning: High-brightness through-hole LED beads with uniform light emission, providing an effective viewing distance of 1–800 meters and enabling clear identification of signals from afar.
Core pain points that can be addressed for clients
Solution: Reduce the frequency of accidents caused by drivers running yellow lights or applying emergency brakes at intersections.
The system intuitively displays the remaining seconds, enabling drivers to anticipate traffic conditions in advance, thereby reducing aggressive driving and sudden braking incidents and lowering the incidence of traffic accidents at intersections.
Solution: Improving visibility of countdown digits when viewing from a distance at major intersections.
400 mm large light-emitting surface ensures a long viewing distance; the countdown time can be clearly read even from large trucks or at distant lanes.
Solution: Address the issue of disorganized installation and uncoordinated appearance of traditional external countdown timers.
This is a single-lamp unit with identical specifications, which can be directly integrated into a signal light assembly or combined with red, yellow, and green signal lights for unified installation; the mounting components are neatly arranged, ensuring a clean and orderly appearance at the intersection.
400MM traffic light two aspectWiring Instructions
Red line
The Red Light Line provides power input to the red LED module, ensuring proper illumination of the red light.
Green line
Green light line – independently controls the green LED module, enabling individual switching of the green light source.
Black line
The public neutral conductor, which serves as the common terminal for the circuit loop, must be reliably connected to the power supply neutral conductor.
Wide-range voltage
Supports a wide input voltage range of AC 85–265 V, compatible with power grid voltage standards worldwide.
Product Installation (Vertical Installation Example)
Nut Assembly – Disassembly
The lamp features built-in screws at both ends; first, remove the screw and its nut.
Fixed L-shaped bracket
Align the flat ends of the two L-shaped brackets with the luminaire mounting holes, then insert the screws into the slots. Tighten the nuts.
Whole-unit component installation
Drill holes in the signal light pole; insert the matching screw through the pole; secure the assembled L-shaped bracket to the pole; tighten the lock nut to complete installation. Tighten the nut.
Usage Precautions
This product features a PC plastic casing; avoid applying excessive pressure to prevent damage to the casing. The device must be powered on only under the supervision of a qualified professional; do not disassemble or assemble the luminaire without authorization.
Usage Instructions & After-Sales Warranty
Usage Instructions
The 125mm three-aspect traffic light features a high-strength sheet-metal casing coated with electrostatic spray paint; avoid applying excessive pressure or subjecting it to severe impacts to prevent damage or deformation. The installation, wiring, and power-on procedures for the luminaire must be performed under the guidance of a qualified professional electrician. Non-professional individuals are advised not to disassemble or assemble the unit independently, as this may lead to circuit malfunctions or electric shock hazards.
Warranty Commitment
We provide a 3-year original manufacturer's warranty to ensure the proper functioning of the luminaire's main structure and core light source; however, wear-and-tear components (e.g., lampshades, connecting cables) and customized non-standard products are not covered under this warranty.
Repair Submission Process
For the customer return-to-service model, please first contact our after-sales customer service to register the fault details; upon receiving authorization, please return the product to a designated service center or send it back to the manufacturer via courier for professional inspection and repair.
Disclaimer
Damage resulting from human-induced damage, unauthorized modification, improper use, or force majeure events (such as fire, earthquake, or voltage abnormalities), as well as malfunctions caused by failure to operate the device in accordance with the instruction manual, are not covered under the free warranty.
Logistics Responsibility
For product repairs, the one-way shipping cost incurred when sending the product from the customer to the after-sales service point shall be borne by the customer; for defects identified during inspection as falling within the warranty scope, the shipping cost for returning the repaired product shall be covered by the brand owner.
