For the 2017 Nissan Titan, the high-beam headlight uses a 9005 bulb. Low-beam fitment depends on the headlight assembly: models with halogen headlights use H11, while models with LED headlights use an LED unit.
Fog-light listings include H11 LED and H16 LED options, so compare the existing bulb and housing before ordering. Front turn signals use 7444NA. Parking-light fitment also follows the headlight type: halogen-headlight models use 7444NA, while LED-headlight models use LED.
Additional notable fitments include 921 for the reverse lights and one brake-light application, with PW16W also listed for the brake lights. The center stop light, license-plate light, trunk light, and door-mirror light are listed as LED. The daytime-running light uses P13W, the tail light uses 3057R, and the rear turn signal uses 3057. For the glove-box light, compare the original bulb because both 2721 and 74 are listed.
