The Volvo S90 parking light utilizes bulb size 7443, 1034NA, or 1157NA depending on the specific version of the vehicle. Available data for the lighting components covers the period from 1997 through 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo S90 front parking light specifications reference three bulb types across the listed model years: the 7443, 1034NA, and 1157NA.
The 7443 is the most frequently specified bulb in these listings, covering the 2017-2021 model years in one or more fitment conditions.
The 7443 is a dual-filament wedge bulb following the T20 form factor, rated at 12V with a 21W high filament and a 5W low filament, and it conforms to ANSI standards for the US and Canadian markets.
The T20 wedge base of the 7443 differs from the BAY15d bayonet base used by the 1034NA and 1157NA, meaning these bulb families are not interchangeable despite sharing the same 12V, 21W/5W electrical ratings.
The 2018-2019 model years carry a fitment condition specifying the 7443 only for vehicles equipped with Halogen Capsule Headlamps, indicating that headlamp type is a relevant variable when selecting the correct front parking light bulb for those years.
The 1034NA and 1157NA are both dual-filament bulbs with a BAY15d bayonet base, rated at 12V and 21W/5W, and both feature natural amber glass, which produces a colored output without the use of a separate amber lens.
The 1034NA is classified as a variant of the 1157, sharing its BAY15d base and electrical ratings while incorporating the natural amber glass of the NA designation.
The Volvo S90 (1998) specifies the 1034NA, while the 1997 model year specifies the 1157NA, placing two closely related but distinct bulb types in consecutive model years for the same application.
