2020 Lincoln Nautilus Bulb Size

Decision: This page lists the bulb sizes and fitments for a 2020 Lincoln Nautilus to help you identify the correct replacements quickly and reduce installation uncertainty. Constraints: vehicle trim variations and aftermarket labeling inconsistencies create ambiguity, so the list emphasizes factory specifications and common alternates to limit misidentification. Options and comparison: bulbs are shown by circuit (headlamp, fog, turn, brake) with standard types such as halogen H11, H7, and various wedge and bayonet fittings, plus LED upgrade options. The comparison highlights differences in light output, heat, and socket compatibility, presenting evidence and noting limitations where compatibility adapters or resistors may be required. Recommendation and risks: follow the factory size first and consider upgraded LEDs only when socket fit and heat management are confirmed, as incorrect choices can cause fitment or electrical issues.
