Jeep Cherokee Map Light Bulb Size

Additional Notes

• The Jeep Cherokee map light draws from five distinct bulb types across its model history: the 12961, 214-2, 212-2, 906, 912, and 561.
• The 212-2 is the most frequently specified bulb in these records, covering the Jeep Cherokee from 2014-2023 with the exception of 2022, making it the dominant fitment across the modern generation of this vehicle.
• The 212-2 and 214-2 are both festoon-style bulbs sharing the same 41mm length and SV8.5 base, operating at 12V and 12W. The SV8.5 base uses metal end caps that make contact at each end of the bulb rather than a pin or wedge fitting.
• Despite their near-identical physical and electrical specifications, the 212-2 and 214-2 carry separate ANSI designations, and the specifications list them for different model years rather than treating them as interchangeable.
• The 906 is a T10 miniature wedge bulb rated at 12V and 8W. It is the most frequently appearing bulb in the earlier portion of the Cherokee's history, covering 1985-1992 and again in 1999 and 2001.
• The 12961 is a Philips-designated T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. At 5W, it draws notably less power than the 906, which shares the T10 form factor but is rated at 8W.
• The 561 is a festoon bulb with end-cap contacts, rated at 12V and 12W, with a 44mm length. Its 44mm length differs from the 41mm length of the 212-2 and 214-2, meaning these festoon types are not physically interchangeable despite sharing the same wattage and voltage.
• The 912 is a T15 wedge bulb rated at 12V and 12W, classified as a variant of the 921. The T15 form factor is physically larger than the T10 used by the 906, and the two wedge types are not interchangeable.
• The 1997 and 1994-1993 model years share the 561 festoon bulb, while the surrounding years in that era use either the 906 or 912, reflecting variation in fitment even within closely spaced model years.
• Across the full span of these specifications, the Cherokee map light voltage remains consistent at 12V regardless of bulb type, while wattage varies from 5W on the 12961 up to 12W on the 214-2, 212-2, 912, and 561.
