When in doubt, consult a Ford dealer or an automotive parts professional with your VIN or trim level.

While H11 low beams and 9005 high beams cover many North American 2010 Focus models, European or other-market versions may use different bulbs (for example, H7, H1, or other base types) for certain headlights or fog lights. Always verify with official documentation or the bulb you currently have installed.
Summary
