For B2B traffic light procurement, certifications are not just paperwork — they are the legal and technical basis for shipping a product to a given market. A certificate you cannot read or cannot verify is no certificate at all. This guide walks through the certifications GAOQIAO products carry most often, what each one actually covers, which jurisdictions require them, and the practical questions to ask any supplier before signing a purchase order.
These four are the baseline for cross-border B2B traffic signal trade. If a supplier cannot provide all four on request, treat that as a red flag.
| Certification | Region | What it covers |
|---|---|---|
| CE | EU + EEA + several other markets accepting CE | EU Low Voltage Directive, EMC Directive, RoHS — electrical safety, electromagnetic compatibility, hazardous substance restriction |
| RoHS | EU + global alignment | Restriction of Hazardous Substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE) |
| FCC | United States | Federal Communications Commission EMC compliance for unintentional radiators |
| IP65 or higher | Global (IEC 60529) | Ingress Protection rating for dust and water |
GAOQIAO products ship with all four. View the certification page for copies of the certificates themselves.
CE is not a quality mark or an approval by an authority — it is a self-declaration by the manufacturer that the product meets all applicable EU directives. For LED traffic lights, three directives typically apply:
To legally affix CE, the manufacturer compiles a technical file containing circuit diagrams, component BOM, test reports, risk assessment and a Declaration of Conformity. EU customs can request this file at any time. If a supplier says "we have CE" but cannot produce the file, the CE is not valid.
IP (Ingress Protection) ratings are defined by IEC 60529. The two digits are independent:
For most traffic signal installations, IP65 is the baseline. Coastal areas with salt spray, tunnel portals and flood-prone intersections benefit from IP66 or IP67. Underground parking and submerged applications require IP68. The LED traffic light product line carries IP65 standard with IP67 available on request.
CE marking demonstrates compliance with EU directives; it does not certify that the product meets any specific performance standard. For traffic signal optical and mechanical performance, the relevant European standard is EN 12368 ("Traffic control equipment - Signal heads"). EN 12368 covers luminous intensity, color, beam pattern, phantom class, mechanical strength and environmental testing.
Other regional product standards include:
For a deep-dive on these standards, see the ITE technical resources library and the EN 12368 standard listing.
For solar traffic lights, the battery is a separately certified sub-assembly. Common battery certifications include:
Traffic light controllers in some jurisdictions also require type approval from the road authority. GAOQIAO controllers are designed to common international interfaces and can be type-approved per project.

Yes, CE marking is mandatory for traffic signals placed on the EU market. It covers the EU Low Voltage Directive, EMC Directive and RoHS Directive. The supplier must compile a technical file, sign a Declaration of Conformity, and affix the CE mark to the product. GAOQIAO products ship with full CE technical files.
IP65 means dust-tight and protected against low-pressure water jets from any direction. IP67 means dust-tight and protected against temporary immersion in water up to 1 meter depth for 30 minutes. For most traffic signal installations, IP65 is sufficient. IP67 is specified for flood-prone intersections, tunnel portals and underground parking entries.
No. CE is an EU compliance mark and is not a global certification. Each country or region has its own system: the US uses FCC for electromagnetic compatibility, Canada uses IC, Japan uses PSE, Australia uses RCM, Brazil uses INMETRO. For B2B export, confirm the destination country's specific requirements before shipment.
There is no fixed expiry on the certificate itself, but the underlying standards are revised periodically. Most EU directives have been updated in the last 5-10 years. Suppliers are expected to maintain the technical file to the current standard revision. Always check the date on the test report, not just the certificate.
