The Indian Chief Vintage uses 1156 bulb size for both front and rear turn signal applications. The replacement chart covers 2009 to 2013 model 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 Indian Chief Vintage uses the 1156 bulb type for both front and rear turn signals across the 2009-2013 model years.
The 1156 is an ANSI-standardized bulb type recognized in the United States and Canada, operating at 12 volts and 21 watts.
As a single-filament bulb, the 1156 serves only one lighting function per socket, which is consistent with its dedicated turn signal application on the Chief Vintage.
The 1156 uses a BA15s bayonet base, a single-contact mount where the bulb locks into the socket with a twist, as opposed to a screw or wedge base design.
The uniform use of the 1156 across all listed model years means front and rear turn signal bulbs on the Chief Vintage are interchangeable with one another within the 2009-2013 range.
The BA15s designation indicates a single contact point at the base, distinguishing it from the BA15d, which carries two contact points and is used for dual-filament applications.
At 21 watts, the 1156 falls within the standard wattage range for incandescent turn signal bulbs, a factor relevant when considering LED replacements, as mismatched wattage can trigger hyperflashing in load-sensitive turn signal circuits.
