The Volkswagen e-Golf uses 7440NA and 12174NA bulb sizes for front turn signals and 7440 bulb size for rear turn signals. The replacement chart covers 2015 through 2019 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volkswagen e-Golf front turn signal uses two distinct bulb types depending on the model year: the 7440NA for 2019 and 2015, and the 12174NA for 2016-2018.
The 7440NA is an ANSI-standardized single-filament wedge bulb in the T20 form factor, rated at 12V and 21W, with natural amber glass that produces a yellow-orange light output without the need for an amber-tinted housing.
The 12174NA is an OEM part number designation rather than an ANSI standard, and it carries a natural amber glass construction rated at 12V, distinguishing it from generic aftermarket classifications.
The 7440 shares the same T20 single-filament wedge form factor and 12V, 21W electrical rating as the 7440NA, with the key difference being the absence of natural amber glass, meaning the 7440 produces clear white light.
Because the 7440NA and 7440 differ in glass tint, substituting one for the other may affect the color of the turn signal output, which is relevant to compliance with lighting regulations in certain jurisdictions.
The front turn signal fitment for the 2019 Volkswagen e-Golf specifies the 7440NA exclusively for vehicles equipped with halogen capsule headlamps, indicating that headlamp type is a determining factor in bulb selection for that year.
The 2015 front turn signal application specifies the 7440NA for vehicles with LED daytime running lights, meaning the lighting configuration of the vehicle directly governs which bulb size applies.
The rear turn signal across the 2015-2018 Volkswagen e-Golf uses the 7440 consistently, with no conditional fitment notes tied to headlamp or lighting system variants.
The 12174NA, used in the 2016-2018 front turn signal position, is defined by an OEM part number rather than an ANSI code, which may affect cross-referencing when sourcing replacement bulbs through non-OEM suppliers.
The 2019 model year marks a departure from the 12174NA used in prior years, with the front turn signal position reverting to the ANSI-coded 7440NA, a bulb type also specified for the 2015 model year front position.
