⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty should be claimed if, after correct installation and vehicle compatibility verification, one of the bulbs exhibits a manufacturing defect, such as not lighting up, burning out prematurely (within the specified period) without signs of misuse, or showing internal failure not resulting from incorrect installation or physical damage. Refer to the seller's warranty and marketplace return policy.
