For the 2017 Nissan 370Z, both the low-beam and high-beam headlights use D2S bulbs. The supplied fitment data does not list separate bulb sizes for different headlight types, so verify the original bulb and headlamp assembly before ordering.
The front turn signals use 7444NA bulbs, while the rear turn signals use amber 7440A bulbs. Reverse lights use 921 bulbs. The brake lights, center stop light, daytime running lights, tail lights, and front and rear side markers are listed as LED.
License plate and parking light fitment is listed as either 168 or 917, so compare the existing bulb before replacement. Interior fitment includes 194 or 7441 for the map lights, 158 for the trunk light, and either 2721 or 74 for the glove box; compare the original bulb for that application.
