Scion FR-S Parking Light Bulb Size

The Scion FR-S parking light utilizes 7443NA and 7444NA bulb sizes for the specific lighting components located on the exterior of the vehicle. Data for the bulb sizes covers the range from 2013 to 2016.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Scion FR-S uses two closely related bulb types for its parking lights across the 2013-2016 model years: the 7443NA and the 7444NA.
Both the 7443NA and 7444NA are ANSI-standardized dual-filament wedge bulbs in the T20 form factor, rated at 12V with a 21W/5W power split between their two filaments.
The natural amber glass construction of both bulb types produces a colored output without the use of a painted or coated lens, as the tint is built into the glass envelope itself.
The dual-filament design allows a single bulb to serve two lighting functions simultaneously, with the higher 21W filament typically handling the brighter signal function and the lower 5W filament handling the steady parking light function.
The 2014 Scion FR-S takes the 7444NA, while the 2013, 2015, and 2016 model years take the 7443NA, meaning the 2014 model year is not interchangeable with the surrounding years despite the bulbs sharing the same T20 base and electrical ratings.
Although the 7443NA and 7444NA share identical voltage, wattage, base type, and glass color, they carry distinct ANSI part numbers, and substituting one for the other without confirming fitment compatibility is not advised.
