Additional Notes

The Ford Escape map light specifications cover model years 2001 through 2012, split across two distinct bulb types depending on the generation of the vehicle.
The 2008-2012 Ford Escape uses the 12961 bulb, a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The T10 wedge base design means the bulb is held in place by friction from its plastic wedge-shaped base, with no separate metal socket pins required for electrical contact.
The 2001-2007 Ford Escape uses the 578 bulb, an ANSI-standard festoon type rated at 12V and 12W, with a 41mm length and end-cap contacts.
A festoon bulb makes electrical contact through metal caps at each end of the cylindrical glass envelope, requiring a holder that grips both ends rather than a wedge-style socket.
The 578 draws 12W compared to the 12961 at 5W, meaning the earlier Escape map light circuit operates at more than twice the wattage of the later generation.
The two bulb types are not interchangeable. The wedge base of the 12961 and the end-cap contact design of the 578 require physically different lamp holders, making substitution between them incompatible without modification.
The 578 is classified under the ANSI standard, giving it broad availability across the US and Canadian automotive market under a consistent part designation.
The 12961 designation is a Philips-assigned part number rather than an ANSI code, though the underlying T10 wedge format is a widely recognized bulb category used across many vehicle makes.
