This 2005 Subaru Impreza bulb size guide helps you quickly verify the correct bulb by lighting position, so you can match the right part before you buy. Because Subaru used different bulbs across trims, body styles, and lighting packages, it is important to check the exact location on the car rather than assuming one bulb fits every lamp.
Use this page as a reference for common exterior and interior lights on the 2005 Subaru Impreza, including headlights, parking lights, turn signals, brake lights, license plate lights, dome lights, map lights, and cargo-area lighting. The listed bulb sizes are organized by position to make replacement easier for sedan, wagon, WRX, WRX STI, and Outback Sport applications where applicable.
Fitment can vary by trim, package, and market, so always compare the bulb in your vehicle with the listing before ordering. This is especially important when switching between halogen and LED replacements, since some aftermarket LED bulbs may fit physically but still need the correct base, polarity, or load handling to work properly. If your Impreza has an aftermarket headlight or fog light conversion, the bulb type may differ from the factory setup, and some conversions use different low beam or fog light sizes than original equipment. The safest approach is to inspect the installed bulb first, confirm the base and shape, and then purchase replacements that match both the bulb type and the lamp location.
The listed high beam bulb for the 2005 Subaru Impreza is 9005. This applies to the high beam position, so it should not be confused with the low beam bulb on trims that use a different setup.
For the Outback Sport, the low beam bulb listed is H1. This is trim-specific, so it may differ from other 2005 Impreza versions.
The 2005 Subaru Impreza WRX STI uses D2R for the low beam headlight bulb. This is a different bulb type from the Outback Sport low beam listing.
The front turn signal bulb listed for the 2005 Impreza is 7440. Always confirm the socket and lens position before replacing it, especially if the car has been modified.
The rear turn signal bulb is listed as 7440A for most 2005 Impreza applications. Wagon rear turn signals use a different bulb, listed separately as 1156A.
The license plate light bulb options listed are 168 and 917. Either may appear depending on the exact lamp setup, so checking the installed bulb is a good idea before ordering.
Both the dome light and map light use DE3175 on this page. That makes it easier to replace both interior overhead bulbs with the same size when needed.
The trunk or cargo area light is listed as 921. There is also an alternate listing of 912 for some cargo-area applications, so verify the bulb already installed in your car.
The center high mount stop light is listed as 921 for RS sedan applications, while Outback Sport is listed with 912. Because this varies by body style, check the exact trim and lamp housing.
The sedan brake light bulb is listed as 7440R. Wagon brake lights are listed differently, so sedan and wagon owners should not assume the same bulb size.
For the wagon, the brake light bulb is listed as 7443R. This is different from the sedan brake light listing, so body style matters here.
The tail light bulb listed on this page is 7443R. As with other rear lighting, confirm whether your car is a sedan or wagon before buying replacements.
The back up reverse light bulb listed is 7440. This is the bulb size shown for the reverse lamp position on the 2005 Subaru Impreza.
The front side marker light bulb is listed as 168NA. The rear side marker light also uses 168NA, so both positions share the same bulb size on this page.
The front fog light bulb is listed as H3C, H3. Because fog light setups can vary, it is best to confirm which version is installed before purchasing.
