If you are looking up bulb sizes for a 2011 Ford Focus, this page is designed to help you match the correct bulb by lighting position instead of guessing from the old bulb alone. The Focus could use different bulbs depending on trim, body style, and lighting equipment, so checking each location on the vehicle is the best way to confirm fitment.
Use the chart on this page to compare the headlight, tail light, brake light, turn signal, fog light, interior, and cargo-area bulb positions for the 2011 Ford Focus. That makes it easier to replace one bulb at a time and avoid buying the wrong size for a specific lamp housing.
Fitment can vary on the 2011 Ford Focus by market, trim, and lighting package, so always verify the bulb already installed before placing an order. Some positions may use halogen bulbs, while others may be listed as LED or may be converted to LED with aftermarket parts. If you are changing from halogen to LED, check polarity, bulb depth, and whether the new bulb will fit inside the housing without causing glare or warning issues. For the most reliable result, remove the old bulb and compare its base and shape to the replacement before purchase.
