Additional Notes

The Chevrolet Blazer stepwell light uses the 906 bulb across all listed model years, spanning 1995-2003.
The 906 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts and 8 watts.
It belongs to the T10 miniature wedge family, a base type that connects by friction fit rather than by a twist-lock or bayonet mechanism.
At 8 watts, the 906 draws relatively low current, which is consistent with its role in a courtesy or entry-area lighting position.
The T10 wedge form factor is shared by several other bulb numbers, though wattage and voltage ratings differ between them, making direct substitution inadvisable without confirming matching electrical specifications.
The stepwell light position illuminates the entry step area when a door is opened, and the 906 serves this function consistently across the entire 1995-2003 span recorded in the specifications.
