This page covers bulb size information for the 2017 Subaru BRZ and is organized by lighting position so you can quickly verify the correct replacement for each lamp. Whether you are replacing a failed bulb or planning a full lighting refresh, checking the bulb chart by location helps reduce guesswork and makes it easier to match the right fit.
The 2017 Subaru BRZ uses a mix of LED lighting and a few conventional bulb types, depending on the position. Because front and rear lighting can differ, this page is meant to help you confirm the bulb size for headlights, signals, markers, interior lights, and cargo-area lighting before you buy parts.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm what is actually installed on your BRZ before ordering replacements. Some positions on this model are listed as LED, while others use standard bulb sizes such as 921, 168/917, DE3175, or 194NA, and aftermarket LED conversions may change the bulb style or require additional compatibility checks. If your car has been modified, or if you are unsure whether a previous owner changed the lighting setup, inspect the existing bulb and connector before purchase to avoid ordering the wrong part.
