The Chevrolet LCF uses a 1156NA bulb size for both front and rear turn signal applications. The replacement chart covers 2016 through 2019 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet LCF uses the 1156NA bulb for both front and rear turn signals across the 2016-2019 model years.
The 1156NA is a single-filament bulb, meaning it serves one lighting function rather than combining two functions such as stop and tail in a shared housing.
The bulb operates at 12 volts and 21 watts, which is consistent with standard automotive incandescent turn signal applications.
The 1156NA uses a BA15s bayonet base, a single-contact base type that differs from the dual-contact BA15d base found on two-filament variants such as the 1157.
The natural amber glass of the 1156NA produces its amber turn signal color directly from the bulb itself, rather than relying on a colored lens to filter a clear light source.
The ANSI designation on the 1156NA confirms the bulb meets standardized specifications recognized in both the United States and Canada.
Because the front and rear turn signal positions share the same 1156NA specification on the LCF, a single bulb type serves all four turn signal sockets on the vehicle.
The BA15s base is not interchangeable with the BA15d base without modification, so substituting a dual-contact 1157-type bulb in place of the 1156NA is not a direct fitment.
