400mm and 500mm traffic signals: specification and purchase checklist
Select the indication and complete assembly before requesting a quotation. A diameter identifies the optic size, not the housing dimensions, operating voltage or compatibility with an existing installation.
| Selection | Options to specify | 需索取的证据 |
|---|---|---|
| 信号显示 | Ball, arrow, pedestrian, bicycle or lane control; aspect count and countdown if required | Selected model and approved signal schedule |
| Supply and control | Rated AC/DC input, controller output and countdown interface | Input rating, terminal drawing and compatibility review |
| Housing and installation | Material, orientation, bracket and cable entry | Dimensioned drawing and mounting arrangement |
| Optical and environmental requirements | Required performance classes and site conditions | Applicable model-specific test reports and configuration scope |
| Purchase scope | Module, complete head, brackets, controller and spares | Itemized configuration, quantity and packing details |
Review traffic signal size selection 和 the wiring checklist. Our workshop, packing and loading photographs show existing factory activity. Request the selected model’s specification and a quotation with your drawing, indication schedule, voltage, quantity and destination.
Choosing 400mm and 500mm LED Traffic Lights for Highway Approaches
400mm and 500mm LED traffic lights are used where a large signal indication is needed for approach visibility. This range includes ball, arrow, pedestrian, bicycle, lane-control, and countdown configurations. The final configuration should be selected around the road layout, controller, voltage, and mounting design.
Selection checklist
- Choose 400mm or 500mm optics according to the project design and local standard.
- Confirm the indication type: ball, arrow, pedestrian, bicycle, or lane control.
- Provide voltage, controller interface, mounting method, and required housing material.
For a faster quotation
- Send the intersection drawing or signal schedule.
- State the quantity by signal face and any countdown requirement.
- Include the delivery country and target project date.
Request a configuration review: send your drawings and requirements to our traffic signal team.
