Additional Notes

The Ram 1500 uses two distinct bulb types for its courtesy lighting across the years covered in these specifications: the 906 and the 212-2.
The 906 is a T10 miniature wedge bulb rated at 12V and 8W, conforming to ANSI standards recognized in both the United States and Canada.
The 212-2 is a festoon-style bulb with a 41mm length and an SV8.5 base, also ANSI-rated, operating at 12V and 12W, drawing 50 percent more wattage than the 906.
The Ram 1500 (2023-2024) uses the 906 wedge bulb for courtesy lighting, while the 2018-2020 model years use the 212-2 festoon bulb.
Wedge bulbs such as the 906 are retained by friction in their sockets, whereas festoon bulbs like the 212-2 are held in place by spring-loaded end caps, making the two types physically incompatible with each other's sockets.
Because the 906 and 212-2 differ in both base type and wattage, they are not interchangeable between the earlier and later Ram 1500 model years represented in these specifications.
