Additional Notes

The Oldsmobile Silhouette map light bulb specifications span model years 1990 through 2004, covering three distinct bulb sizes across that range: 168, 562, and 906.
The 168 bulb is the most widely used type in these specifications, fitted to the Oldsmobile Silhouette across model years 1997-2004.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, conforming to ANSI standards for the US and Canadian markets.
The 562 bulb is the second most frequently specified type, appearing in the 1991-1993 and 1995-1996 model years.
Unlike the wedge-style bulbs in these specifications, the 562 is a festoon bulb measuring 44mm in length with end-cap contacts, rated at 12V and 12W, making it physically and electrically distinct from the other two types listed.
The 906 bulb is also a T10 miniature wedge type, sharing the same base form factor as the 168, but rated at a higher 8W output at 12V.
Although the 168 and 906 share the T10 wedge form factor, their wattage ratings differ, 4.9W versus 8W respectively, which is a relevant consideration for direct substitution.
The 906 bulb is specified for the 1990 and 1994 model years of the Silhouette, both of which fall between years that use the 562 festoon type.
All three bulb sizes in these specifications conform to ANSI standards applicable in both the United States and Canada.
The festoon-style 562 and the wedge-style 168 or 906 are not interchangeable, as they use fundamentally different mounting and contact configurations.
