The 2015 Nissan Altima SV uses different bulb types depending on whether your car has halogen headlights (most common) or the optional projector/HID setup.

Below is a complete breakdown so you can order the correct bulbs the first time.

 Low Beam Headlight

 Halogen Version (Most Common SV Models)

• Bulb Size: H11

• Type: Single beam (low beam only)

 Factory HID Version (If Equipped)

• Bulb Size: D2S

• Type: Xenon HID

 If you’re unsure, look at your headlight housing:

• If it has a round projector lens and says “HID”, you likely have D2S.

• If it uses a standard reflector bowl, it’s H11.

 High Beam Headlight

• Bulb Size: 9005

• Type: Halogen (even if low beam is HID)

The high beam is separate from the low beam on the Altima.

 Fog Lights (If Equipped)

• Bulb Size: H11

• Found in the lower bumper.

 Turn Signals

• Front Turn Signal: 7444NA

• Rear Turn Signal: 7440

(If upgrading to LED, make sure to use load resistors or anti-hyperflash bulbs.)

 Brake Lights

• Bulb Size: 7443

 Reverse Lights

• Bulb Size: 921

 Interior Lights

These vary slightly, but commonly:

• Map / Dome: 194 or DE3175 (varies by location)

Quick Reference Chart

If you’re planning an LED or HID upgrade, let me know which lights you want to change. I can also recommend the best performing options based on beam pattern and brightness.
