Installation Notes

Verify the bulb base type, contact count, wattage, and vehicle position before installation. This part uses a twist-type PU20d/6 base, so the socket must match the original design. Confirm the application by year, make, model, and position, especially on vehicles with lighting-package variations such as HID headlights or halogen capsule headlights noted in the fitment data.

For service matching, this part cross-references common OE-style lighting applications where the same bulb specification is required. The part number HPC24WNAC1 should be checked against the original bulb marking before replacement.
