About GAOQIAO

Related traffic signal resources

Use these resources to prepare product questions and project requirements. Confirm electrical and installation details against the documentation for the selected model.

Related resources

Use the download library alongside the model documents

The resources above cover signal materials, LED types, regional applications and purchasing decisions. Start with the subject relevant to the decision you need to make. Material comparisons help organise housing questions, while LED guides help identify the optical and electrical information to request for a proposed signal.

A general article is not a substitute for the wiring or installation instructions for a particular controller or head. Keep the product model, drawing revision and document reference together when sharing information with the purchasing or installation team. This makes it easier to check that everyone is reviewing the same configuration.

Information to bring to the review

  • For housing selection, compare the proposed material, assembly drawing and evidence required by the project.
  • For LED selection, request the data for the finished signal configuration rather than comparing LED names alone.
  • For controller instructions, match the document to the controller model and electrical version.
  • For quotations, retain the selected product link and a list of documents still needed before approval.

Send the relevant model links and project information through GAOQIAO contact. Keep the final product configuration and document list attached to the quotation for that project.
