For the 2014 Jeep Patriot, the low-beam and high-beam headlights both use an H13 bulb. The supplied fitment data does not list a separate projector or non-projector headlight variation, so confirm the existing bulb before ordering if the vehicle has replacement or aftermarket headlamp assemblies.
Other useful exterior bulb sizes include 3757A for the front turn signals, parking lights, and front side markers. The rear turn signal uses a 3157, while the rear tail and brake lights use 3157R. The rear side markers use 3157A.
The reverse lights take 921 bulbs. License plate lighting is listed with two possible sizes, 2825 and 98, so check the socket and original bulb before replacement. The center stop light is listed as LED rather than a replaceable bulb size. Interior dome, map, and trunk lights each use a 578 bulb. No fog-light bulb fitment is provided in the supplied data.
