ANSI standard (US & Canada). Single-filament bulb with BA15s bayonet base. 12V, 21W.	1156

The Ford Contour uses the 1156 bulb for the back up light across the 1995-2000 model years.
The 1156 is an ANSI-standardized bulb type, meaning its 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 reverse lighting applications.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, as opposed to dual-filament types that handle two functions such as braking and running light simultaneously.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a bayonet mount with a 15mm base width and a single contact pin, distinguishing it from the visually similar BA15d, which carries two contact pins for dual-filament use.
Because the BA15s base accepts only a single contact, substituting a dual-contact bulb such as the 1157 into the same socket is not electrically compatible, even though the physical fit may be close.
