## Before you buy

- The listing is inconsistent about the application: the title and part number identify H4/9003 bulbs, while the light-source and feature descriptions call them fog lights and repeatedly mention top clearance marker assemblies. Confirm the exact socket, beam use and vehicle fit before purchase. The 40000-lumen, 600% brighter, compatibility, waterproofing and lifespan statements are listing claims, not verified results.
