Buick Park Avenue Map Light Bulb Size

Additional Notes

• The Buick Park Avenue map light uses two distinct bulb types across its model years: the 214-2 for 1997-2005 and the 562 for 1991-1993.
• Both the 214-2 and 562 are festoon-style bulbs, meaning they are cylindrical in shape and mount horizontally between two contact points within the fixture.
• Both bulbs operate at 12 volts and 12 watts, placing them in the same electrical category despite their physical differences.
• The 214-2 bulb measures 41mm in length and uses an SV8.5 base, which features a metal cap that slots into a dedicated socket.
• The 562 bulb measures 44mm in length and uses end-cap contacts, meaning the electrical connection is made through metal caps at each end of the bulb rather than through a keyed socket base.
• The 3mm difference in length between the 214-2 and the 562 means the two bulbs are not interchangeable, as festoon fixtures hold bulbs under spring tension calibrated to a specific length.
• The differing base types of the two bulbs further prevent cross-substitution, since the SV8.5 socket of the 214-2 fixture is physically incompatible with the end-cap design of the 562.
• Both bulbs conform to ANSI standards applicable in the United States and Canada, indicating standardized performance and dimensional tolerances within their respective types.
