Headlight Assembly API | OEM Part Numbers & Fitment by VIN

Find the right headlight assembly without the guesswork. Get OEM part numbers, side-specific fitment, and detailed compatibility data by VIN or year, make, and model.

Avoid Headlight Fitment Errors Before They Become Returns

Two vehicles with the same model year can have different headlight assemblies because of equipment, trim, lighting technology, or optional packages.

0 %

86% of returns in automotive ecommerce are caused by fitment errors.

0 %

20-30% typical return rate for online auto parts stores.

0 %

5-10% return rate for stores with proper fitment filtering.

0 %

67% of consumers won’t return after a bad return experience.

The Solution: Better Fitment Data

Many fitment-related returns trace back to the same root cause: a part number chosen without knowing which variant the vehicle actually has. Checking fitment data catches that before the order ships, not after it’s returned.
