Volvo V50 front fog light bulbs utilize H8 and H11 sizes, while rear fog light bulbs use P21W size specifications. The replacement chart covers vehicle production from 2005 through 2011 with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo V50 front fog light uses two different bulb types depending on the model year, with H8 fitted in 2008-2011 models and H11 fitted in 2005-2007 models.
The H8 and H11 are not interchangeable despite both being single-filament halogen bulbs under the ECE standard. They use different base types, with the H8 using a PGJ19-1 base and the H11 using a PGJ19-2 base.
The H8 operates at 12V and 35W, while the H11 operates at 12V and 55W, meaning the H11 draws significantly more power and produces a higher wattage output than the H8.
Both the H8 and H11 carry ECE approval for use in Europe and worldwide, and both also hold approval for use in the United States.
The Volvo V50 rear fog light uses the P21W bulb across all model years from 2005-2011, making it the only rear fog light specification for this vehicle.
The P21W is a single-filament signalling bulb rated at 12V and 21W, operating at a lower wattage than either front fog light bulb type used on the V50.
The P21W uses a BA15s bayonet base, which is a single-contact bayonet fitting, distinguishing it entirely from the PGJ19-series bases used by the H8 and H11.
The P21W also conforms to the ECE standard, placing all three bulb types used on the V50 within the same international regulatory framework.
