For the 2011 Nissan Sentra, the low-beam and high-beam headlights both use an H13 bulb. This fitment data does not specify a separate projector or non-projector headlight variation, so verify the original bulb before ordering if the housing has been changed.
Front fog lights are listed with two options: H11 LED and H16 LED. Check the existing fog-light bulb and socket to confirm which option matches your vehicle. The front turn signals and parking lights use 3457A, while the front and rear side markers use 194NA.
At the rear, the brake and tail lights use 3057R, and the rear turn signals use 3057. Reverse lights use 921. The center stop light may use a 921 bulb or an LED assembly; compare it with the original before replacement. License plate and map lights may use either 168 or 917. Interior applications include DE3175 for the dome light and 158 for the glove-box and trunk lights.
