Kia Amanti Turn Signal Bulb Size

Additional Notes

• The Kia Amanti rear turn signal specification uses two closely related bulb types across its model years: the 2357 and the 2357NA.
• Both the 2357 and 2357NA are ANSI-standard dual-filament bulbs rated at 12V with a high-filament draw of 26.9W and a low-filament draw of 8W.
• Both bulb types share the BAY15d bayonet base, a two-pin offset base design that ensures correct orientation during installation.
• The 2357 is a brighter variant of the common 1157 bulb, producing higher light output while maintaining the same base configuration.
• The 2357NA differs from the standard 2357 solely in its natural amber glass envelope, which filters the light output to produce an amber color without relying on a tinted lens or housing.
• The Kia Amanti (2004-2006) rear turn signal specification calls for the 2357NA, meaning the amber tint is built into the bulb itself rather than the vehicle's lens.
• For the 2007-2009 model years, the rear turn signal specification shifts to the clear-glass 2357, indicating those model years use an amber-tinted lens or housing to achieve the required signal color.
• Substituting a 2357 for a 2357NA in a 2004-2006 Amanti, or vice versa in a 2007-2009 model, risks producing an incorrect signal color output, as the amber tinting function is distributed differently between the bulb and the lens depending on the year.
