Additional Notes

The Chevrolet LCF uses the 1156 bulb for the back up light across the 2016-2019 model years.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard shared across the United States and Canada.
The 1156 operates on a 12-volt electrical system and draws 21 watts, which is consistent with standard automotive incandescent back up light applications.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, as opposed to dual-filament types that can handle two functions such as stop and tail simultaneously.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a bayonet mount with a 15mm collar and a single contact pin, which determines physical fitment into the socket.
The BA15s base is not interchangeable with the BA15d base, which carries two offset contact pins rather than one, so substitution between these two base types is not possible even when the collar size matches.
