200mm Single-Faced Four-Light Portable Traffic Light

Name: 200mm Mobile Single 4-Light Light
Availability: InStock

The 200mm solar-powered single-sided four-light portable traffic signal is designed for use at intersections. It requires no cable connections, eliminating the need for road excavation or overhead wiring. It offers exceptional mobility, allowing the signal to be moved freely and positioned at any intersection where emergency response is needed. It is suitable for urban road intersections and can be used during power outages or construction to direct the flow of vehicles and pedestrians. Its purpose is to temporarily direct vehicles to follow traffic rules, ensuring smooth and orderly traffic flow; to temporarily regulate traffic volume, improve traffic capacity at intersections, and reduce traffic accidents.Single-lane mobile traffic lights require a pair of lights for use (one for each direction of approach and departure). The two lights are connected wirelessly, and users can set the green light duration, the shared red light duration (when both directions display red), the yellow light duration, and the all-red mode.

Intelligent Charge/Discharge Protection: Features a built-in smart controller with automatic protection against reverse connection, overcharging, over-discharging, and short circuits, effectively extending battery lifespan.

200mm Mobile Single 4-Light Light

The Model 200 mobile single-sided four-light unit (temporary traffic signal) is a temporary emergency traffic control device primarily used for road construction, emergency power restoration at intersections, temporary road closures, and temporary traffic diversion at school entrances and exits. 200mm Mobile Single 4-Light Light operates without external mains power, relying instead on an integrated battery and solar panels for charging. The unit features a pushable mobile base, allowing flexible repositioning to suit different operational sites. 200mm Mobile Single 4-Light Light is equipped with a wireless remote controller for signal timing control, and the signal unit itself incorporates an LED digital tube countdown display that shows the remaining travel time in real time. (See the figure below)

Features of the Model 200 Mobile Single-Sided Four-Light Product

Red, yellow, and green traffic signal outputs: red light prohibits passage, yellow light provides a warning buffer, and green light permits passage; this configuration enables basic traffic control at intersections and simulates the operation of real-world traffic signal systems for managing vehicular flow.

LED digital countdown display feature: The digital display beneath the signal lights shows in real time the remaining time for the current phase; drivers can clearly see the remaining seconds, which helps reduce lane-merging and emergency braking, thereby enhancing traffic safety at intersections.

Solar panel charging + built-in battery storage: During daytime, the built-in battery is charged via rooftop solar photovoltaic panels; on cloudy days and at night, the system continues to operate using the built-in battery; no external 220V mains power is required, and no wiring is needed—making 200mm Mobile Single 4-Light Light ideal for temporary use in outdoor or construction site environments.

On-site remote configuration of timing: allows direct wireless adjustment of the red light duration, green light duration, and yellow light flashing duration, eliminating the need to climb the equipment for debugging.

Wireless master-slave synchronization feature (Key): Enables wireless communication pairing between two signal units, with one unit configured as the master and the other as the slave; this facilitates bidirectional alternating signal control at intersections (one side operates on red, while the other side synchronizes on green, as illustrated), allowing for the temporary deployment of bidirectional intersection signal systems.

Mode switching: switch between the flashing yellow warning mode (construction warning) and the normal traffic light cycling mode.

The core pain points addressed by the Model 200 mobile single-sided four-light unit for customers

There is no mains power available at the construction site, making 200mm Mobile Single 4-Light Light impossible to install fixed signal lights.

Powered by solar energy combined with a built-in battery, this system requires no road excavation for cabling and no connection to a 220 V mains power supply; once deployed on-site, 200mm Mobile Single 4-Light Light can be put into operation immediately.

Construction sites frequently change locations, whereas fixed signal lights cannot be relocated.

The base of the push cart features universal casters; once the workstation position has been adjusted, the equipment can be directly moved by hand; this design facilitates repeated relocations.

The temporary intersection lacks signal control, posing a safety liability risk.

Equipped with comprehensive red, yellow, and green signal indicators along with a countdown display, enabling drivers to anticipate the remaining time for passage; this helps standardize vehicle traffic flow and reduce the risk of traffic accidents for construction contractors.

Significant traffic diversion pressure following signal light failures or power outages.

Can be rapidly deployed to fault intersections for emergency operation, swiftly taking over traffic control at the intersections to alleviate the pressure on traffic police officers conducting manual on-site direction.

Wiring Instructions for Model 200 Portable Single-Sided Four-Light Unit

Product Installation (Vertical Installation Example)

Solar panel installation:

Assemble the solar panel with the solar mounting bracket and tighten the screws; then, install the solar panel—once the bracket is in place—onto an angled bracket and tighten the screws accordingly. If the portable lamp is equipped with only one solar panel, use an angled bracket to mount the solar panel onto the lamp pole, as shown in the figure on the lower left.

Lighting fixture installation:

Install the sunshade cap on the upper part of the lamp: place the sunshade cap over the lamp and tighten 200mm Mobile Single 4-Light Lightusing screws aligned with the corresponding holes;
Each end features a screw; unscrew the nut on the screw, slide the L-shaped bracket over the screw, and secure it with the nut.
The lamp post features a hole for a screw; drill holes in the L-shaped bracket of the lamp according to the hole positions, insert an appropriate screw through the lamp post, slide the L-shaped bracket over the screw, and secure it with a nut.
