Nissan Altima Headlight and Bulb Sizes

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

The headlight bulbs on a Nissan Altima is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

What headlight bulb does a 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 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.
