The Volvo S60 Cross Country front turn signal uses a 12174SV bulb size, while the rear turn signal requires either a 12496 or PY21W bulb size. The replacement chart covers 2016 through 2018 model 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 Volvo S60 Cross Country uses two distinct bulb types across its front and rear turn signal positions for the 2016-2018 model years.
The front turn signal on the 2016-2018 S60 Cross Country takes the 12174SV across all three model years, indicating no change in front fitment during this period.
The 12174SV is a Philips SilverVision part number referencing an enhanced coating halogen bulb rated at 12V. The enhanced coating is a factory-applied treatment that alters the bulb's visible appearance while maintaining halogen light output.
The rear turn signal for the 2017-2018 S60 Cross Country uses the 12496, a 12V halogen bulb designated for specialty applications under both Philips and Osram part numbering systems.
The 2016 S60 Cross Country rear turn signal uses the PY21W, which is an ECE-standard bulb type rather than a manufacturer-specific part number. ECE designations are used across European and international markets as a standardized classification.
The PY21W features a BAU15s bayonet base, which is an offset single-pin base. The offset pin prevents the bulb from being seated in sockets intended for the straight-pin BA15s base, making cross-installation physically incompatible.
The PY21W is rated at 21W and produces amber light through a tinted glass envelope, as opposed to clear-glass bulbs that rely on an amber lens for color output.
Because the 2016 rear turn signal uses the PY21W and the 2017-2018 uses the 12496, these two bulb types are not interchangeable for the rear position despite both being 12V halogen sources.
