For the 2015 Lincoln Navigator, the low-beam and high-beam headlights both use D3S bulbs. The supplied fitment data does not list a separate halogen bulb option or a fog-light bulb for this model year, so confirm the existing headlamp configuration before ordering.
Several exterior lights are listed as LED, including the front parking lights, daytime running lights, front and rear side markers, tail lights, rear turn signals, reverse lights, and brake lights. The front turn signal also has a 906NA listing, indicating a fitment variation that should be matched to the vehicle’s current socket or lamp assembly.
Other listed bulbs include 2825 or 98 for the center stop light, dome light, and map light; 168 or 917 for the license-plate lights; and 194 or 7441 for the glove-box light. The trunk light uses 211-2. Check the removed bulb and lamp assembly when multiple options are listed.
