This 2019 Subaru WRX bulb size page is designed to help you verify the correct bulb for each lighting position before you buy replacements. Because the WRX can use different headlight and fog light setups depending on trim, package, market, and body style, it is important to match the bulb to the exact location on the car rather than assuming one size fits every version.
Use the chart on this page to quickly find the bulb type for your 2019 Subaru WRX by lighting position, including headlights, fog lights, turn signals, reverse lights, license plate lights, interior lights, and more. The WRX may be equipped with LED lighting or halogen lighting, and the correct bulb size can change based on that equipment.
For the best fitment results, always compare your WRX’s installed bulb with the chart before ordering. Trim and lighting package differences can change the bulb type, especially between halogen headlights and LED headlights, and some fog light setups may also vary with eyesight or steering responsive fog equipment. If you are converting from halogen to LED aftermarket bulbs, make sure the replacement is compatible with the housing and local road-use rules, since not every LED retrofit performs the same way. When possible, check the old bulb, connector, and housing style first so you can avoid buying the wrong part and save time on installation.
