Additional Notes

The Buick Park Avenue uses the 214-2 bulb for the dome light across the 1997-2005 model years.
The 214-2 is a festoon-type bulb, meaning it is cylindrical in shape and mounts by pressing lengthwise between two spring clips or contact holders.
The 214-2 measures 41mm in length and uses an SV8.5 base, which refers to a smooth-ended cap that seats into a bayonet-style festoon socket.
The 1991 and 1993 Park Avenue dome light takes the 562 bulb instead, which is also a festoon type but measures 44mm in length.
The 562 uses end-cap contacts rather than an SV8.5 base, making it physically and electrically distinct from the 214-2 despite sharing the same 12V, 12W electrical rating.
Because the 214-2 and 562 differ in both length and contact design, the two bulbs are not interchangeable across the model years in which each is specified.
Both the 214-2 and 562 conform to ANSI standards applicable in the United States and Canada.
Both bulbs operate at 12 volts and 12 watts, which is consistent with standard automotive low-voltage interior lighting systems.
