Honda Fit Parking Light Bulb Size

Additional Notes

• The Honda Fit parking light specifications cover model years 2009-2012 and 2015-2020, spanning two distinct bulb type generations.
• Three bulb types appear across these specifications: the 7444NA, 7443NA, and 194NA, all of which conform to ANSI standards recognized in the United States and Canada.
• The 7444NA is the most frequently specified bulb, covering the Honda Fit for model years 2016-2017 and 2019-2020.
• The 7444NA and 7443NA are both dual-filament T20 wedge bulbs rated at 12V with a 21W high filament and a 5W low filament, and both feature natural amber glass rather than a clear envelope with a coated or colored lens.
• Natural amber glass produces an amber output directly from the bulb itself, which is a construction method distinct from bulbs that rely on an external amber housing or lens to produce the same color.
• The 7443NA is specified for the 2015 and 2018 Honda Fit, and while it shares the same T20 form factor, dual-filament design, and electrical ratings as the 7444NA, the two carry different ANSI designations and are not confirmed interchangeable by these specifications.
• The 194NA is specified for the 2009-2012 Honda Fit and represents a significantly different bulb class from the 7444NA and 7443NA, as it is a single-filament T10 miniature wedge bulb rated at 12V and 3.78W.
• The lower wattage of the 194NA (3.78W) compared to the 21W/5W dual-filament T20 bulbs reflects a fundamental difference in socket size, filament count, and light output between the earlier and later Fit generations covered in these specifications.
• The T10 and T20 designations refer to the bulb body width in millimeters multiplied by two, meaning a T10 wedge base is narrower than a T20, and the two form factors are physically incompatible with each other's sockets.
