Additional Notes

The Dodge 600 uses the 1156 bulb across all listed model years, spanning 1983-1988.
The 1156 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
As a single-filament bulb, the 1156 serves one dedicated function per socket, which in this application is the backup light circuit.
The 1156 operates at 12 volts and 21 watts, consistent with standard 12V automotive electrical systems.
The BA15s bayonet base on the 1156 features a single locating pin on the base collar, which distinguishes it from dual-pin bayonet variants and makes it non-interchangeable with those types.
The BA15s base designation means a replacement bulb must match this specific base configuration to seat and make proper electrical contact in the socket.
