For the 2014 Dodge Grand Caravan, both the low-beam and high-beam headlights use an H11 bulb. The supplied fitment data does not identify a projector or non-projector headlight variation, so no headlight-type distinction is specified here.
The daytime running lights are listed as H11 LED, while the fog lights use 2504 LED bulbs. At the front, the turn signals and parking lights use 3757A, and the front side markers use 2827.
Other useful replacement sizes include 3157 for the reverse lights and 168 for the license plate lights. Interior applications include 194 for the courtesy and glove-box lights, 578 for the dome, reading, and interior lights, and PC579 for the map lights. The instrument panel uses PC74. For the trunk light, compare the original bulb before ordering: the listed options are 578 and 561.
