Ford Focus Bulb Size By Years

Decision: This chart identifies compatible bulb sizes for a 2011 Ford Focus so you can match replacements accurately, minimizing trial-and-error and avoiding lighting mismatches. The purpose is evidence-based clarity rather than exhaustive technical deep-dive. Constraints and options: The list is limited to common OEM and aftermarket sizes; an interpretation of manufacturer guidance and observed fitment informs each entry. Options include standard halogen, upgraded halogen, and LED-compatible sizes, with noted limitations where adapter use or housing compatibility becomes relevant. Comparison, recommendation, and risks: Compare sizes by socket type and brightness potential to choose a fit that balances legality and heat management; my recommendation favors matching OEM size unless a tested upgrade has documented compatibility.
