OE 811941029F — Headlight for Hyundai / Kia

Aftermarket headlight comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

Every shipment of 811941029F leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Yes. Sample lots of 811941029F are used by QC teams to benchmark dimension, material and finish before a volume commitment. Send the reference and we will quote the sample alongside the production price.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a headlight the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.
