Additional Notes

The 906 bulb follows the ANSI standard recognized in the US and Canada. It is a miniature wedge type in the T10 form factor, rated at 12 volts and 8 watts.
The 212-2 bulb also carries ANSI standardization for the US and Canada. It is a festoon type with a 41mm length and an SV8.5 base, rated at 12 volts and 12 watts.
The Ram 1500 Classic uses two distinct courtesy bulb types across its model years, with the 906 wedge and the 212-2 festoon representing different physical formats and wattage ratings that are not interchangeable with each other.
The SV8.5 base on the 212-2 is a festoon-specific mounting standard, while the T10 wedge base on the 906 relies on friction-fit contacts rather than a dedicated base socket, reflecting a fundamental difference in installation method between the two bulb types.
