2019–2025 Nissan Altima Headlight and Bulb Sizes

Which Nissan Altima model years does this cover?

These headlight bulbs specifications apply to every Nissan Altima built from 2019 through 2025 — the L34 (6th generation), mid-size sedan (fwd; awd available with 2.5l). Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What headlight bulb does a 2019–2025 Nissan Altima use?

H11 (halogen S/SV/SR base headlamps); sealed LED on SL, Platinum, Edition ONE and later SR trims, no user-replaceable bulb for the low beam and 9005 (HB3) on halogen headlamps; LED otherwise for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

Can you put LED bulbs in a 2019–2025 Nissan Altima?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
