How the 2021 compares with nearby years
Against the 2020 Sentra: The low-beam bulb and high-beam bulb are the same in both manuals.
Against the 2022 Sentra: The low-beam bulb and high-beam bulb are the same in both manuals.
The H11 low-beam bulb appears in every Sentra manual from 2015 to 2025 that this site has read (11 model years).
The 2021 Sentra belongs to the 8th gen (B18), which began with the 2020 model year (MY2024 facelift: new front/rear fascias and headlights); generation dates. Parts often carry over within a generation, but the manual for your exact model year is the one to trust.

What the manual does not print
The 2021 Nissan Sentra owner's manual does not list wipers, battery, filters and oil sizes; for the battery, read the label on the battery fitted to the car, then check the size against the BCI group chart; for wipers, measure each blade end to end and buy the nearest whole-inch size.
Buying the parts for a 2021 Sentra
- Headlight bulbs: the H11 low beam and the H9 high beam are halogen capsules on trims that have them; buy them in pairs so both sides match in colour and output.
- Small bulbs: this manual names 7 replaceable bulb positions. Wedge bulbs such as W5W and 194 differ from twist-socket bulbs such as 7443 or 3157, so match the full number, including suffixes like NA (amber).
