Plan compatible parts with the signal configuration
Traffic signal accessories and spare parts are easiest to source when they are matched to the original signal-head, mounting and controller specification. For maintenance, replacement and new installation projects, the key information is not only the part name: the signal diameter, number of sections, housing arrangement, voltage, lens or visor requirement, mounting interface and project quantity all affect compatibility.
Use a clear list when requesting parts. Include the traffic signal head type, dimensions, indication layout, existing controller or cabinet reference, mounting photo or drawing, desired replacement item and delivery destination. This helps distinguish a replacement requirement from a new signal assembly and avoids ordering a component that does not fit the installed equipment.
For a complete signal-head specification, read the traffic signal head guide. If the parts must work with a junction controller, review the Ассортимент дорожных контроллеров and submit the project information through our request-a-quote form. GAOQIAO can then review the configuration before preparing a compatible quotation.

Build a parts list that separates the assemblies
For a repair order, group items by the equipment on which they will be installed. A lens, LED module, housing and bracket may belong to the same signal but require separate identifiers. Photograph the part before removal where practical, and keep the original nameplate reference with its measurements.
Mark which components must be reused and which are being replaced. A module-only quotation should not be compared directly with a complete signal-head quotation. Include the intended quantity of service spares and the documents needed by the maintenance team. Before approving a batch, agree how the supplied part will be checked for fit, electrical compatibility and the required indication.
