For the 2000 Nissan Altima, both the low-beam and high-beam headlights use a 9007 bulb. The same 9007 fitment is also listed for the daytime running lights. No projector or non-projector headlight distinction is provided, so verify the original bulb before ordering if the headlamp assembly has been replaced or modified.
The front fog lights use 881 bulbs. Front turn signals take 3457A bulbs, while rear turn signals use 3156. The brake and tail lights use 3157R, with 3157 listed for the parking and cornering lights. The front side markers use 194NA bulbs.
For the center stop light, compare the original bulb before purchase: the listed options are 921 or LED. Reverse lights use 921 bulbs. License plate lighting may use either 168 or 917, so match the bulb currently installed. Interior applications include DE3175 for the dome light, 658 for the glove-box light, 578 for the map light, and 158 for the trunk light.
