If you need bulb sizes for a 2017 Subaru Outback, this page is designed to help you verify the correct fit by lighting position. The Outback can use different bulbs depending on the headlight type and equipment package, so checking the exact location is the best way to avoid ordering the wrong part.
Use the listings below as a practical reference for common exterior and interior bulbs on the 2017 Outback. Whether you are replacing a low beam, high beam, dome light, map light, or cargo area bulb, matching the bulb to the correct lamp position is the key step before purchase.
Fitment can vary by trim, market, body style, and lighting package, so always confirm what is installed on your vehicle before buying. The 2017 Outback may use halogen headlights or HID headlights, and fog light setups can differ as well, especially on models with the EyeSight package or steering responsive fog lighting. If you are considering an aftermarket LED conversion, make sure the bulb type, connector style, and housing compatibility all match your setup, since not every LED replacement will work correctly in every reflector or projector housing. When possible, remove the old bulb and compare it directly before ordering.
