For the 2012 Dodge Grand Caravan, both the low-beam and high-beam headlights use an H11 bulb. The supplied fitment data does not list a projector or non-projector headlight distinction, so verify the original bulb before ordering if the vehicle has replacement or non-factory headlamp assemblies.
The daytime running lights use H11 LED bulbs, while the fog lights use 2504 LED bulbs. Front and rear turn signals, as well as the parking lights, use 3757A. The front side markers use 2827, and reverse lights use 3157.
For interior and exterior utility lighting, the license plate lamps use 168, courtesy and glove-box lights use 194, and the dome, interior, and reading lights use 578. Map lights use PC579, while instrument lighting uses PC74. The trunk light may use either 561 or 578; compare the existing bulb before replacement.
