How do I verify a Chinese LED traffic light manufacturer is legitimate?

Ask for their business license and verify it on China's National Enterprise Credit Information Publicity System. Order a paid sample before any bulk order, and consider a third-party factory audit through SGS, Bureau Veritas, or QIMA for large orders.

What's the typical MOQ for LED traffic lights?

Most manufacturers require an MOQ of 50–100 units for standard products. Custom or OEM products may have higher MOQs (200–500 units), but some manufacturers offer lower MOQs for repeat customers or pilot projects.

How long is the production lead time?

Standard products typically ship within 15–25 days after deposit. Custom OEM/ODM orders usually take 30–45 days depending on complexity. Add 25–40 days for ocean shipping to most destinations.

Do LED traffic lights come with a warranty?

Reputable manufacturers offer 3–5 year warranties on traffic signal heads. Some offer extended warranties up to 5–7 years for premium products. Always get warranty terms in writing.

Can a Chinese manufacturer meet U.S. or European standards?

Yes. Many Chinese LED traffic light manufacturers hold CE, RoHS, FCC, ITE, and EN 12368 certifications. The key is to verify the certificates are current, valid, and issued by accredited labs — not self-declared.
