Traffic Signal Solutions and Product Selection

Choose traffic signal products by road-user application, signal size, indication type and system requirement. Each page combines relevant GAOQIAO products with a practical specification checklist.

Choose a solution category

Start with the project function rather than a catalogue photograph. Use the guides below to compare signal sizes, road-user indications, controller requirements and temporary or solar operating conditions. Each guide links to relevant GAOQIAO products and lists the technical information needed before a configuration can be confirmed.

Build the signal system from approved requirements

A traffic signal head, controller, mounting structure and power supply operate as one system. The same nominal diameter can contain a ball, arrow, pedestrian, bicycle or countdown indication, and similar-looking products may use different voltages, wiring methods or mounting dimensions. For this reason, the applicable standard, junction drawing and signal schedule should take priority over a product name.

For temporary and solar projects, also confirm daily operating hours, sunlight conditions, required autonomy, wireless distance and the safe behavior after a communication or power fault. For fixed intersections, provide the phase plan, controller model, output schedule and mounting layout. GAOQIAO can review these details before a quotation is finalized.

Prepare a precise inquiry

Provide the project drawing, signal schedule, required standard, voltage, controller information, mounting arrangement, quantity and destination. Product names and photographs alone are not enough to confirm system compatibility. A confirmed drawing should show the indication layout, overall dimensions, mounting points, cable entry and requested accessories.
