Honda Fit front side marker bulbs use 168 or 194NA sizes, while rear side marker bulbs use 7443 or 168 sizes. The replacement bulb size chart covers 2007 through 2020 model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Fit uses three distinct bulb types across its front and rear side marker positions: the 168, the 194NA, and the 7443.
The 168 and 194NA are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage and glass treatment. The 168 draws 4.9W through clear glass, while the 194NA draws 3.78W through natural amber-tinted glass.
The natural amber glass of the 194NA produces a yellow-orange light output without the use of a colored lens or housing filter, which is the functional distinction between it and the standard 168.
The 7443 is a T20 dual-filament wedge bulb rated at 12V with a 21W high filament and a 5W low filament, making it physically and electrically incompatible with the T10-based 168 and 194NA bulbs.
The Honda Fit (2015-2020) uses the 168 bulb for the front side marker position.
The 2009-2012 front side marker position uses the 194NA, which is a T10 wedge form factor but is not a direct substitute for the 168 due to the amber glass coating and lower wattage rating.
The rear side marker on the 2009-2012 Fit uses the 7443, a dual-filament T20 bulb, which is a larger format than the T10 bulbs used in the front side marker positions of the same model years.
The 2007-2008 rear side marker position uses the 168 bulb, the same T10 single-filament type specified for several front side marker applications across other model years.
All three bulb types listed carry the ANSI standard designation applicable to the US and Canadian markets.
Because the 7443 is a dual-filament bulb, it supports two independent brightness levels within a single housing, a characteristic not shared by the single-filament 168 or 194NA bulbs.
