This 2017 Toyota Yaris bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right part the first time. Whether you are changing a headlight, interior bulb, or rear lamp, using the correct bulb size matters for fit, brightness, and safe operation.
The Yaris can use different bulb setups depending on trim, market, and body style, so it is smart to match the bulb to the exact location on the vehicle. This page organizes the common bulb sizes for the 2017 Toyota Yaris in a simple way that makes comparison and replacement much easier.
Before buying, confirm whether your 2017 Toyota Yaris uses halogen or LED lighting in the area you are servicing, since some positions may already be LED while others use replaceable bulbs. Trim level and lighting package can change the bulb type, and aftermarket LED conversions may require different fitment or additional hardware. For the best results, check the bulb currently installed in the vehicle and compare it with the chart before ordering, especially for headlights, fog lights, and exterior signal lamps.
The headlight bulb listed for both high beam and low beam on the 2017 Toyota Yaris is 9003. Always confirm the exact lamp setup on your car before purchase, since lighting configuration can vary by market and trim.
The front turn signal light bulb is 7444NA. This same bulb size is also listed for the parking light on the 2017 Toyota Yaris.
The rear turn signal light bulb is 7440. If you are replacing one side, it is often a good idea to check the opposite side so both lamps match in age and brightness.
The brake light bulb and tail light bulb are both listed as 7443R. That makes it easier to replace either function with the same bulb size, depending on which lamp needs service.
The back up reverse light bulb is 921. This is the bulb to check if your reverse lights are dim, out, or flickering when the vehicle is in reverse.
The license plate light bulb is listed as 168 or 917. Either size may appear depending on the exact lamp assembly, so it is best to verify the installed bulb before ordering.
Both the dome light bulb and map light bulb are listed as 168 or 917. These are common interior bulb sizes, but the exact fit can still depend on the trim and overhead console design.
The front side marker light bulb is 168NA. This is separate from the front turn signal and parking light bulb, even though some exterior bulbs may look similar.
The rear side marker light bulb is 7443A. If you are replacing rear exterior lighting, make sure you are matching the correct side marker bulb and not the brake or tail lamp bulb.
The front fog light bulb may be H11 LED, H16 LED, or H8 LED depending on the vehicle configuration. Because fog light setups can differ, checking the installed bulb is especially important here.
Yes. The center high mount stop light is listed as LED, and the daytime running light bulb is listed as LED with 9003 also shown in the chart. This means some lighting positions may already be LED, while others still use replaceable bulbs.
The trunk or cargo area light bulb is DE3022. If your Yaris has this lamp and it is not working, confirm the socket style and bulb length before buying a replacement.
Because trim, package, and market differences can change the bulb size on a 2017 Toyota Yaris. Checking the installed bulb helps avoid ordering the wrong part, especially for headlights, fog lights, and interior lighting.
