Nissan GT-R front turn signal bulbs use 2357NA, 7444NA, or 7443NA sizes, while rear turn signal bulbs require 7440NA size. The replacement bulb chart covers 2009 through 2024 model years with corresponding specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The rear turn signal position on the Nissan GT-R uses the 7440NA across all model years covered in the specifications, from 2009 through 2024. This bulb is a single-filament T20 wedge type rated at 12V and 21W with natural amber glass, conforming to the ANSI standard for the US and Canada market.
The front turn signal position draws from three different bulb types across the same model year range, reflecting hardware variation between production years rather than a single standardized fitment.
The 7443NA and 7444NA are both dual-filament T20 wedge bulbs rated at 12V with a 21W high-filament and 5W low-filament output. Both carry natural amber glass and meet the same ANSI standard, making their electrical and physical profiles nearly identical within the T20 wedge format.
Despite their near-identical specifications, the 7443NA and 7444NA are not confirmed as interchangeable in these specifications. The GT-R front turn signal position alternates between the two across different model years, and substituting one for the other without verifying socket compatibility could result in an improper fit.
The 2357NA, specified for the Nissan GT-R front turn signal in 2023-2024, differs fundamentally from the T20 wedge types used in earlier years. It uses a BAY15d bayonet base rather than a wedge base, operates at a higher wattage of 26.9W on its primary filament, and is physically incompatible with sockets designed for T20 wedge bulbs.
The shift to the 2357NA in 2023-2024 means the front turn signal socket type changed from the wedge format used in prior model years. A bulb from a pre-2023 front turn signal position cannot be installed in a 2023-2024 front socket, and vice versa.
All four bulb types in these specifications use natural amber glass to produce their amber output. This construction method differs from clear-glass bulbs paired with amber-tinted housings or amber-coated lenses, and it is a factor relevant to legal compliance in markets that regulate turn signal color at the bulb level.
The 7440NA used at the rear is a single-filament bulb, while the front positions across all years use dual-filament types. This distinction means rear and front turn signal bulbs on the GT-R are not interchangeable regardless of model year, as the filament count and base configurations do not match.
