Honda CR-V Parking Light Bulb Size

Additional Notes

• The bulb size 168 is the most frequently specified front parking light for the Honda CR-V, covering model years 1997-2007 across a span of eleven years. It is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W.
• The 12961 is a Philips-designated part number for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It is specified for the Honda CR-V in 2019 and 2021-2022, and its wattage is marginally higher than the 168 bulb it effectively replaces in later model years.
• The 7443NA, 1034NA, and 1157NA bulbs are all dual-filament types rated at 12V with a 21W high-filament and 5W low-filament output. This dual-filament configuration allows a single bulb to serve both parking and turn signal functions within one housing.
• The 1034NA is documented as a variant of the 1157NA, sharing the same BAY15d bayonet base and the same 12V, 21W/5W electrical rating. Both carry natural amber glass, which produces an amber output without requiring an amber-tinted lens or housing.
• The 7443NA uses a T20 wedge base rather than the BAY15d bayonet base found on the 1034NA and 1157NA. Although all three share the same dual-filament wattage ratings, their bases are physically incompatible, making them non-interchangeable despite similar electrical characteristics.
• The "NA" suffix on the 7443NA, 1034NA, and 1157NA designations indicates natural amber glass coloring. This is a distinct product variant from the clear-glass equivalents (7443, 1034, and 1157), and substituting a clear-glass version would alter the color output of the parking light.
• The T10 wedge base is shared by both the 168 and the 12961 bulbs, though the 12961 specifies the more precise W2.1x9.5d base designation. The physical compatibility of these two bulbs in the same socket depends on whether the socket tolerances accommodate both variants.
