2003 Rolls-Royce Phantom Bulb Size

As a risk steward, I put this bulb size chart together to help owners of the 2003 Rolls-Royce Phantom find the right lamp quickly. The baseline is simple: bulb sizes vary by function and submodel, and a wrong fit may dim lights or stress sockets. This list shows common OEM sizes and notes where the Phantom can differ. Edge cases can include optional packages, aftermarket conversions, or model year quirks. You may find different bulbs for fogs or interior lights on some cars. Detect by checking your owner’s manual, the bulb housing markings, or carefully removing the lamp to confirm type. Mitigation is straightforward: choose bulbs with matching base and compatible wattage, or use a safe default like OEM-equivalent parts.

Quick checklist: verify part number, confirm wattage, prefer OEM-equivalent, and test fit before final installation.
