Kia Telluride Parking Light Bulb Size

Additional Notes

• The 1157NA is a dual-filament bulb operating at 12 volts with a 21W/5W power rating, meaning it draws 21 watts on its high-intensity filament and 5 watts on its low-intensity filament. This dual-filament design allows a single bulb to serve two lighting functions within one housing.
• The 1157NA uses a BAY15d bayonet base, which features two offset pins positioned at different heights on the base. This asymmetric pin arrangement prevents incorrect insertion, ensuring the high and low filaments connect to their correct circuits.
• The natural amber glass of the 1157NA produces its amber color through the glass itself rather than a coating, which generally results in greater color consistency and durability over the bulb's lifespan.
• The 1157NA designation follows ANSI standards applicable in both the United States and Canada, classifying it as a standardized bulb type with defined electrical and physical characteristics across manufacturers.
• The Kia Telluride front parking light uses the 1157NA for the 2021-2022 model years. The "NA" suffix distinguishes this bulb from the standard 1157, and the two are not interchangeable despite sharing the same base type, as the standard 1157 uses clear glass rather than natural amber.
