Additional Notes

The Volvo XC60 backup light specifications cover two distinct bulb types across the model's production span: H21W for the 2021-2024 model years and P21W for the 2010-2018 model years.
Both the H21W and P21W are ECE-standard single-filament signalling bulbs rated at 12V and 21W, meaning they share identical voltage and wattage ratings despite being different bulb types.
The H21W uses a BAY9s base, which is an offset bayonet fitting. The offset pin arrangement of the BAY9s base is designed to prevent incorrect bulb installation.
The P21W uses a BA15s bayonet base, a single-contact bayonet fitting with a 15mm collar. This base type is among the most widely used in automotive signalling applications worldwide.
Although the H21W and P21W share the same wattage and voltage ratings, their bases are physically incompatible. The BAY9s and BA15s fittings are not interchangeable, and substituting one for the other is not possible without modification.
The 2022 model year is absent from the specifications, so no bulb size is attributed to it in this data set.
The 2019 and 2020 model years are similarly absent from the specifications, and no bulb size is attributed to either year in this data set.
Both bulb types conform to ECE regulations, which are recognized across Europe and in numerous markets worldwide, reflecting a standardized approach to automotive lighting used across the XC60 lineup.
