Volvo V90 Cross Country Turn Signal Bulb Size

Additional Notes

• The Volvo V90 Cross Country front turn signal uses two distinct bulb types across its production years: the H11 for 2022-2024 and the PY24WNA for 2017-2021, with the earlier years specifying halogen capsule headlamp fitment as a condition of that application.
• The H11 is an ECE-standard single-filament halogen bulb with a PGJ19-2 base, rated at 12V and 55W. Although it originates from European standardization, it carries approval for use in the United States as well.
• The PY24WNA is an ANSI-standard bulb governed by US and Canadian specifications. It is an amber variant of the ECE PY24W type and uses a PGU20-4 base, rated at 12V and 24W. The base type differs from that of the H11, making the two bulbs physically non-interchangeable.
• The wattage difference between the front turn signal bulbs is substantial. The H11 draws 55W while the PY24WNA draws 24W, reflecting their different functional roles and circuit expectations across model years.
• The rear turn signal on the V90 Cross Country uses the H21W across all listed years from 2021-2024, indicating no change in rear fitment over that period.
• The H21W is an ECE-standard single-filament signalling bulb with a BAY9s base, rated at 12V and 21W. The BAY9s is a bayonet-style base with offset pins, which prevents substitution with bulbs using standard or other bayonet configurations.
• The front and rear turn signal bulbs on the V90 Cross Country share no common base type across any listed year, as the H11 uses PGJ19-2, the PY24WNA uses PGU20-4, and the H21W uses BAY9s.
• For 2017-2019 front turn signal fitment, the PY24WNA specification is conditional on the presence of halogen capsule headlamps, indicating that vehicles equipped with a different headlamp system may require a separate bulb specification.
