The 2019 Subaru Legacy uses a mix of LED and halogen bulb setups depending on the lighting position and the vehicle’s trim or package. This page helps you verify bulb sizes by lighting position so you can match the correct replacement for the headlight, tail light, interior, and exterior lamps on your car.
For the 2019 Legacy, some locations are listed with LED assemblies while others use replaceable bulb sizes such as 9005, H11, 921, 168, 194, 7444NA, 7440A, and DE3175. Checking the bulb chart by position is the easiest way to confirm what fits before you buy replacements.
Fitment can vary by market, body style, and lighting package, so always compare the bulb chart with the actual lamp on your vehicle. Some 2019 Subaru Legacy models use LED units in places where other trims may use a halogen bulb, and aftermarket LED conversions may require additional adapters, resistors, or a different housing to work correctly. Before ordering, inspect the installed bulb and connector whenever possible, especially for headlight, fog light, and turn signal applications, because the same year and model can have different lighting configurations.
The listed low beam bulb size for the 2019 Subaru Legacy is H11 on applicable halogen-equipped models. Some versions use an LED headlight assembly instead, so check your specific trim before purchasing.
The listed high beam bulb size is 9005 on applicable halogen-equipped models. Other versions may have LED headlight assemblies, which do not use a standard replaceable bulb in the same way.
Yes, some 2019 Subaru Legacy models are equipped with LED headlight assemblies for both high beam and low beam functions. Because trim and lighting package differences can change the setup, confirm your exact headlight type before ordering parts.
The front fog light position is listed as LED. If your car has factory LED fog lights, the bulb may be part of the assembly rather than a simple replaceable bulb.
The backup reverse light bulb size is 921.
The license plate light uses 168 or 917.
Both the dome light and map light use DE3175.
The trunk or cargo area light uses 194 or 7441.
The front turn signal light bulb is 7444NA.
The rear turn signal light bulb is 7440A.
The rear side marker light bulb is 168NA.
Yes, the listed parking light and daytime running light positions are LED on applicable models. As with the headlights and fog lights, the exact setup can vary by trim and package.
Not always. If the vehicle uses a factory LED assembly, there may not be a direct halogen bulb replacement. In those cases, the entire lamp design and electrical setup need to be considered before changing parts.
Because the 2019 Subaru Legacy can have different lighting configurations by trim, market, or body style. Checking the installed bulb helps avoid ordering the wrong size, especially for headlights, fog lights, and exterior signal bulbs.
