For the 2014 Dodge Durango, headlight bulb fitment depends on whether the vehicle has halogen or HID headlights. Both the low-beam and high-beam positions use the same bulb type within each setup.
- Halogen headlights: 9012 for both low beam and high beam. The daytime running light also uses 9012, and parking lights use 3157A.
- HID headlights: D3S for both low beam and high beam. The daytime running light, parking light, and several exterior lamps are listed as LED.
- Fog lights: The supplied fitment lists H11 LED and H16 LED options.
- Other notable lighting: Front turn signals use 3157A, reverse lights use 921, and the tail, rear turn signal, brake, center-stop, license-plate, and side-marker lights are listed as LED.
Interior and utility bulbs include 906 for the step light, 2825 or 98 for courtesy lighting, 194 or 7441 for the glove box, 103 for the instrument panel, and 214-2 for the trunk light.
