Halogen headlights: low beam H11, high beam 9005. Factory HID headlights: low beam HID bulbs (D2S or D3S) and high beams vary by trim.
The 2017 Nissan Altima offered both halogen and HID headlight configurations, depending on trim level and options. This article outlines the common bulb sizes for each setup and how to confirm the exact type for your vehicle.
Halogen headlight option
If your Altima is equipped with standard halogen headlights, these are the typical bulb sizes used for the main headlights:
- Low beam: H11
- High beam: 9005
Halogen headlight configurations are common on the base and mid-level trims. Always verify by checking the bulb on your vehicle or consulting the owner's manual.
HID headlight option
For Altimas with factory HID headlights, the low-beam bulbs are HID and require a ballast. The exact HID bulb type can vary by production year and trim, but the two most common possibilities are D2S or D3S. The high-beam arrangement in HID-equipped systems often differs from the low-beam setup and may use a separate halogen bulb in many configurations.
Low beams
Possible HID bulb types used in the 2017 Altima include:
- D2S
- D3S
Because HID systems rely on a ballast, the bulb type alone isn’t enough to guarantee compatibility; verify the exact bulb type by inspecting the existing bulb, checking the service manual, or contacting Nissan support.
High beams
In many HID-equipped Altimas, the high beams are implemented with a separate halogen bulb (commonly 9005) or with a dedicated HID high-beam setup depending on the trim. Confirm the exact configuration for your specific vehicle, as it can vary by model year, trim, and whether an upgrade package was installed.
How to verify the correct bulb size for your car
Because bulb sizes can vary by trim and options, the most reliable method is to confirm with official sources or inspect the vehicle directly:
- Check the owner’s manual for bulb specifications corresponding to your trim and configuration.
- Look at the label on the back of the headlight housing or inside the fuse/relay box area for bulb type information.
- Read the imprint on the bulb itself after removing it from the headlight assembly.
- If in doubt, contact a Nissan dealer or a trusted automotive parts retailer with your VIN to get the exact spec.
Replacing bulbs with the incorrect size or type can cause electrical issues, improper fit, or reduced lighting performance, so it’s worth double-checking before purchasing replacements.
Summary
For 2017 Nissan Altima models with halogen headlights, use H11 for low beams and 9005 for high beams. If the car features factory HID headlights, the low beams require HID bulbs (D2S or D3S), while the high beams’ configuration varies by trim. Always verify exact bulb sizes via the owner's manual, vehicle labels, or Nissan support to ensure a precise match. Proper identification helps ensure optimal visibility and electrical compatibility.
