100MM Portable Wireless Solar Traffic Light With Tripod Light Pole

A mobile traffic light, also called a portable traffic signal or temporary traffic light, is a self-contained signal head mounted on a wheeled or trailer-based platform. It is deployed for temporary traffic control situations where permanent signals are inappropriate or unavailable: construction zones, road work, utility maintenance, emergency response, public events, and film shoots. The mobile design allows one technician to deploy a fully functional signalised intersection in 15-20 minutes, without trenching, cabling, or grid connection. GAOQIAO supplies mobile traffic lights in solar-battery hybrid and pure battery configurations, with optional wireless synchronization between paired units.

How to Choose the Right Mobile Traffic Light

Five variables determine specification:

Deployment duration: Short-term (1-7 days) typically uses pure battery. Long-term (weeks to months) requires solar hybrid to avoid manual recharging.

Traffic volume: Higher volume roads need 300 mm heads for visibility. Low-volume rural or work-zone roads can use 200 mm.

Synchronization requirement: Single-direction alternating (e.g., single-lane road works) needs two paired units with wireless sync. Complex multi-phase control needs a controller-equipped version.

Vehicle maneuverability: Wheeled trolley is for pedestrian-deployment. Trailer with tow hitch is for frequent relocation between sites. Pallet base is for crane deployment.

Local regulations: Some jurisdictions require pre-approval for temporary signals. Specifiers should verify with the local road authority before deployment.

A common mistake is specifying a mobile traffic light for permanent intersection use. Mobile units are designed for short-term deployment; long-term permanent use is the role of fixed 3-aspect LED traffic light or 4-aspect LED traffic light.

Key Features and Benefits

Wireless Pairing for Two-Way Control

Two mobile units can be wirelessly synchronized to provide alternating one-way traffic control on a single-lane road works. The pairing range is 500 m to 2 km line-of-sight, depending on the wireless technology selected. No cables between units means deployment in 15-20 minutes per site.

Solar Hybrid for Long-Term Deployment

The 50-100 W solar panel keeps the battery topped up in normal conditions, providing 5-15 days of autonomous operation even in extended overcast conditions. For 24/7 operation, the unit can be supplemented with a small generator.

Easy Relocation

The wheeled trolley or trailer configuration means one technician can relocate the unit daily if needed. This is valuable for road work that progresses along a road alignment.

Common Applications

Single-lane road works (alternating one-way with paired units)
Construction zone intersections (replacing permanent signals during work)
Utility maintenance (water, gas, telecom)
Emergency road closures (accident response, weather events)
Public events (parades, marathons, festivals)
Film and TV production (temporary road closures)
Bridge repairs (replacing fixed signals during work)
Mine and quarry vehicle control (mobile crossings)

Installation and Maintenance

Deployment: position the unit at the desired location, deploy stabiliser legs or wheel chocks, switch on, configure the timing plan via the front-panel keypad or mobile app. Wireless pairing is automatic within range. Deployment time: 15-20 minutes per unit.

Maintenance: visual inspection every 1-3 months depending on use intensity, battery health check every 6 months, solar panel cleaning as needed. The trailer/trolley mechanical components require standard equipment maintenance (wheel bearings, hitch, etc.).

Certifications and Compliance

Standard documentation: CE/RoHS/FCC, ISO 9001, 1-year warranty on the complete unit. Wireless synchronization certifications (FCC for US, CE-RED for Europe) on project basis. EN 12368 compliance for the signal head itself, but the mobile platform is generally certified as a complete system rather than against road-signal standards.
