6. B2B Procurement FAQ
Q1: How to choose between 12V and 24V automotive LED strips?
A1: 12V DC LED strips are suitable for most civilian fuel vehicles and new energy passenger cars; 24V DC models are dedicated for commercial vehicles such as trucks, buses and RVs. For long-distance wiring scenarios, thickened copper substrate strips are recommended to avoid brightness attenuation.
Q2: What certifications are required for exporting car LED strips to Europe and America?
A2: European markets require CE (EMC+LVD) and RoHS certifications; North American markets support FCC certification; OEM matching projects need IATF16949 system certificates. We can provide complete third-party test documents.
Q3: Can you provide free samples for testing?
A3: Yes, we support free sample provision (customers bear freight cost). Spot samples can be delivered within 1-3 working days, and customized samples take 3-5 working days. The sample fee will be refunded after bulk order placement.
Q4: Will RGB ambient LED strips interfere with original car Bluetooth and car machine signals?
