Xtreme White Hybrid bulbs are worth it if you want the lightest possible. They're brighter and provide better contrast versus stock, allowing drivers to see farther with greater safety on dark roads or high traffic areas like city streets at night time - because these lights don't have any filters that would interfere with their visibility! Made from quality materials such as quartz glass alongside our special alloy filaments which reflect heat much more efficiently than common metals do; this means they will last longer without getting too hot and eventually cracking under pressure (which can lead us to an accident).

The 2017 Ford Focus ST uses different bulbs depending on body style, headlight type, and lighting package, so this page is designed to help you verify the correct bulb size by lighting position. Whether you are replacing a front turn signal, a reverse light, or a headlight bulb, checking the exact location first can save time and prevent ordering the wrong part.

Use the bulb chart for the 2017 Focus ST as a quick reference for hatchback and sedan fitment, including halogen and HID-equipped models. Because Ford used more than one bulb setup on this year, the same lighting function may call for a different bulb size depending on the trim and market.

The 2017 Focus ST can differ between halogen and HID setups, and some aftermarket LED conversions may change the bulb type or require additional adapters, resistors, or housings. Lighting packages can also vary by region, so if your car has been modified or imported, the safest step is to remove the old bulb and confirm the number printed on it before buying a replacement.
