Honda Passport front side marker bulbs utilize 1034NA, 1157NA, or 194 bulb sizes, while rear side marker bulbs use 168 or 1157 sizes. The replacement chart covers 1994 to 2002 production years 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 194 bulb is the most frequently specified front side marker bulb across the Honda Passport lineup, covering the 1994-1999 model years. It is a T10 miniature wedge bulb rated at 12V and 3.78W.
The 1157 bulb serves as the rear side marker across the 1994-1999 model years. It is a dual-filament bulb with a BAY15d bayonet base, rated at 12V and 21W/5W.
The 2001-2002 Honda Passport front side marker uses the 1034NA bulb, which is a dual-filament BAY15d bayonet base bulb with natural amber glass, rated at 12V and 21/5W.
The 1034NA is described as a variant of the 1157. While both share the BAY15d bayonet base and the same 12V/21W/5W ratings, the 1034NA incorporates natural amber glass, whereas the standard 1157 does not.
The 2000 model year front side marker uses the 1157NA, which shares the BAY15d bayonet base and 12V/21W/5W ratings of the 1157 but also features natural amber glass, similar to the 1034NA.
The rear side marker for the 2000-2002 model years uses the 168 bulb, a T10 miniature wedge type rated at 12V and 4.9W. Though it shares the T10 wedge form with the 194, its wattage is higher.
The 194 and 168 bulbs both use the T10 miniature wedge base, which can create a risk of substitution errors. Their wattage ratings differ, with the 194 at 3.78W and the 168 at 4.9W, making them non-equivalent replacements despite the shared base type.
The 1034NA, 1157NA, and 1157 bulbs all use the BAY15d bayonet base. The BAY15d base features two pins offset at different heights, which prevents incorrect single-filament bulbs from being inserted in their place.
The natural amber glass on the 1034NA and 1157NA bulbs produces an amber output without relying on a colored lens. This is relevant for side marker applications where amber light output is required by regulation.
The front side marker position on the Honda Passport transitioned across three different bulb types over the production span, moving from the single-filament 194 wedge through the dual-filament BAY15d variants, indicating a change in socket and housing design between certain model years.
