How to choose an automotive lighting fitting

Start with the original lamp or part reference. A socket label helps narrow a shortlist, but the proposed sample still needs review for the actual vehicle, lamp housing and destination market.

What should I collect first?

Provide the vehicle make, model, year and original lamp or part reference when available. Clear photographs of the existing base, connector and available housing space can help describe the requirement.

Is a matching H4, H7, H11 or 9005 label enough?

No. Use the original reference to identify the required fitting, then review dimensions, mounting, electrical behaviour and beam pattern for the exact configuration. Do not infer interchangeability between different fitting labels.

How should I compare HID and LED conversion listings?

Identify the original lamp technology and its electrical system before comparing the listed HID and LED conversion series. Review installation requirements for the proposed item individually.

Which details belong in an enquiry?

Include the listed series, required fitting, quantity, vehicle or original lamp details and destination country. Describe constraints such as clearance or electrical requirements. The quotation should identify the proposed configuration and the checks still needed.

Compare LED headlight bulbs or fog lights, review sample confirmation checks, then send your sourcing brief.
