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 | Evidence to request |
|---|---|---|
| Signal indication | 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 and 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.
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.
Request a configuration review: send your drawings and requirements to our traffic signal team.
Also available: 300mm LED traffic lights and traffic light size comparison guide.
