Additional Notes

The Dodge Magnum uses the 9005 bulb for high beam headlights across the 2005-2008 model years. This is a single-filament halogen bulb operating at 12V and 65W, fitted with a P20d base, and standardized under ANSI specifications for the US and Canadian markets.
The 9006 bulb serves as the low beam headlight across the same 2005-2008 model years. It shares the single-filament halogen construction and 12V rating of the 9005 but draws 55W and uses a P22d base rather than a P20d base, making the two bulbs physically non-interchangeable despite their similar appearance.
The P20d and P22d base designations on the 9005 and 9006 respectively refer to the physical socket configuration. Because these bases differ in size, the two bulb types cannot be swapped between the high beam and low beam sockets.
The 1978-1979 Dodge Magnum uses sealed beam units rather than replaceable halogen bulbs. In sealed beam technology, the lens, reflector, and filament are fused into a single glass unit, so the entire assembly is replaced rather than just an internal bulb.
The high beam position on the 1978-1979 Magnum takes the H4651, a 4x6-inch rectangular sealed beam unit rated at 12V and standardized under ANSI specifications for the US and Canadian markets.
The low beam position differs between the two earlier model years. The 1979 Magnum uses the H4656 sealed beam unit, while the 1978 Magnum uses the H4652. Both are 4x6-inch rectangular sealed beam units operating at 12V, with the H4652 classified as a variant of the H4651.
Because the H4651, H4652, and H4656 are distinct ANSI part numbers, substituting one for another without confirming compatibility is not advisable, even though the H4652 is described as a variant of the H4651.
