Volvo V60 front turn signal bulbs utilize 12174NA size while rear turn signal bulbs use PY21W or 12496 size. The replacement chart covers 2015 through 2018 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo V60 front turn signal uses the 12174NA bulb across the 2015-2018 model years.
The 12174NA is an OEM part number designating a natural amber glass bulb rated at 12 volts. The "NA" suffix indicates the natural amber tint is built into the glass envelope rather than applied as a coating.
The Volvo V60 rear turn signal does not use a single bulb type across the 2015-2018 range, with two distinct bulb sizes appearing across those model years.
The PY21W is specified for the rear turn signal on the 2016 and 2018 V60. It follows the ECE lighting standard used in Europe and worldwide markets, featuring a single filament, amber glass, a BAU15s offset bayonet base, and a 12V, 21W rating.
The BAU15s base on the PY21W has an offset pin arrangement that physically prevents installation of non-amber standard BA15s bulbs, making it a keyed fitment by design.
The 12496 is specified for the rear turn signal on the 2015 and 2017 V60. It is a part number associated with Philips and Osram and is classified as a 12-volt halogen bulb for specialty applications.
The PY21W and 12496 are not interchangeable without verification, as they carry separate part designations and base type specifications, and the rear turn signal position alternates between them across the 2015-2018 model years.
All three bulb types listed across the V60 turn signal specifications operate on a 12-volt electrical system, consistent with standard automotive low-voltage architecture.
