Volvo C70 front fog light bulbs utilize H8, H11, or H3 size specifications, while rear fog light bulbs require P21W size. The replacement chart covers vehicle production spanning 1998 to 2013 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 C70 front fog light specification calls for three distinct bulb types across its model years: H3, H11, and H8, each representing a different generation of the vehicle's fog lighting setup.
The H3 bulb is a single-filament halogen unit operating at 12V and 35W, fitted with a PK22s base. It holds ECE approval for Europe and worldwide markets, with additional approval in the United States and Japan.
The H11 bulb is a single-filament halogen unit operating at 12V and 55W, fitted with a PGJ19-2 base. It carries ECE approval and is also approved for use in the United States.
The H8 bulb is a single-filament halogen unit operating at 12V and 35W, fitted with a PGJ19-1 base. Although it shares a similar physical profile with the H11, its wattage rating and base type differ, making the two types non-interchangeable.
The Volvo C70 front fog light used the H3 bulb for the 1998 and 2001-2004 model years, the H11 for 2006-2010, and the H8 for 2011-2013, indicating that the correct bulb type is strictly dependent on the model year.
The H11 and H8 bulbs both use PGJ19-series bases, but the PGJ19-2 base of the H11 and the PGJ19-1 base of the H8 are not the same fitting. Substituting one for the other in the Volvo C70 front fog light housing would result in an incorrect fitment.
The P21W is a single-filament signalling bulb operating at 12V and 21W, fitted with a BA15s bayonet base. Its ECE approval covers Europe and worldwide markets.
The Volvo C70 rear fog light uses the P21W bulb across all listed model years from 1998 through 2013, making it the only rear fog light specification present in these data.
The BA15s bayonet base of the P21W is a single-contact fitting. It is not compatible with double-contact bayonet bases such as the BA15d, and the two should not be treated as interchangeable.
All four bulb types listed in the Volvo C70 fog light specifications conform to ECE standards, indicating suitability for markets that require ECE-compliant lighting components.
