Toyota RAV4 Turn Signal Bulb Size

Additional Notes

• The T20 wedge bulb family, which includes the 7440, 7440NA, 7443, 7443NA, 7444NA, and 7444NA types, is the most frequently specified bulb format across the Toyota RAV4 turn signal positions covered in these specifications.
• The 7440 and 7440NA are single-filament T20 wedge bulbs rated at 12V and 21W, while the 7443, 7443NA, 7444NA, and 7444 are dual-filament variants of the same T20 form factor rated at 12V with a 21W/5W output split. Despite sharing the same physical housing style, single- and dual-filament T20 bulbs serve different circuit configurations and are not interchangeable.
• The NA suffix on bulb designations such as 7440NA, 7443NA, 7444NA, 1034NA, and 1157NA indicates natural amber glass, meaning the amber color is produced by the glass envelope itself rather than by an amber-tinted housing or lens. A non-NA bulb of the same base number produces clear or white light and relies on an external amber lens for color output.
• The front turn signal position on the Toyota RAV4 (2001-2003) carries two separate bulb specifications depending on whether the vehicle was built with or without fog lamps. The 7440 is specified for fog lamp-equipped vehicles, while the 7440NA is specified for those without fog lamps, indicating a difference in lens color between the two trim configurations.
• The 1998 Toyota RAV4 front turn signal position carries three distinct specifications tied to production date and location. Vehicles produced to 09/1997 use the 1157 for the main position and the 194 for a side function, while vehicles produced from 09/1997 onward use the 1157NA, reflecting a mid-cycle change in either lens design or market specification.
• The 1157 and 1157NA bulbs share a BAY15d bayonet base and a dual-filament 12V, 21W/5W rating. The 1034NA carries the same BAY15d base and 12V, 21/5W output but is a distinct ANSI type. All three were used on the RAV4 in model years 1996-2000 across the front turn signal and front inner turn signal positions.
• The 1156 is a single-filament bulb with a BA15s bayonet base rated at 12V and 21W. It is specified for the rear turn signal on the 1996-1997 RAV4. The BA15s base is not compatible with the BAY15d base used by the 1157 and 1034NA types, as the two bayonet bases differ in pin offset geometry.
• The 194 is a miniature T10 wedge bulb rated at 12V and 3.78W. In the RAV4 specifications, it appears in the front outer turn signal position for 1998-2000 and as a side front turn signal function for 1998 vehicles produced to 09/1997. Its low wattage distinguishes it from all other bulb types listed, which are rated at 21W or higher.
• The front turn signal on the 2019 RAV4 specifies the 7444NA exclusively for vehicles equipped with Multi LED Headlamps. This condition-based fitment indicates that the headlamp package on that model year affects the front turn signal circuit or housing configuration.
• The front turn signal position on the 2024 RAV4 specifies the 194, while the 2021-2023 model years specify the 7444NA. The rear turn signal on the 2024 RAV4 specifies the 7444NA, the same type used in the rear position for 2022-2023. This means the front and rear turn signal bulb types differ on the 2024 model year.
