200mm交通信号灯

Planning an enquiry for a 200mm signal

Describe the required indication

Use this 200mm traffic-signal gallery reference as a starting point for identifying the equipment you need. Specify the colour and symbol arrangement, the number of sections and whether the order covers a complete head, a housing or an optical module. A nominal 200mm designation does not describe every part of the assembly.

For a project with several signal types, make a separate line for each configuration. Keep vehicle, pedestrian, arrow and countdown requirements clear. Add the project drawing or a marked front-view sketch so that the supplier can distinguish the required arrangement from other products of the same nominal size.

Check the installation dimensions

Provide the proposed mounting arrangement and the space available for the complete head. If the purchase replaces existing equipment, include the model label, bracket measurements and connection details. Request the offered assembly’s drawing before deciding that matching lens diameters will provide a direct replacement.

Confirm the supply and controller interface, including any countdown or dimming requirement. Identify which brackets, visors and cable fittings are included. The quotation should make those boundaries clear so the installer knows what else must be provided.

Request evidence for the selected model

Send the destination specification and required documents with the enquiry. The relevant performance and acceptance requirements apply to the chosen configuration, not to every product appearing in a gallery. Retain the approved model and drawing revision for future spare-part orders.
