This page helps you verify bulb sizes for the 2020 Nissan Altima by lighting position, so you can match the correct bulb before you buy. Because the Altima may use different lighting setups depending on trim, package, and market, checking the exact lamp location is the safest way to avoid ordering the wrong part.
For the 2020 Nissan Altima, the bulb chart includes common exterior and interior positions such as the low beam, high beam, fog light, daytime running light, turn signal, brake light, tail light, license plate light, dome light, and cargo area light. Some positions are LED on many versions, while others may use replaceable halogen-style bulbs, so it is important to confirm the configuration on your specific car.
Fitment can vary between sedan body style, trim level, and lighting package, so use the chart as a guide rather than a substitute for visual confirmation. If your Altima came with factory LED lighting, the bulb may be part of a sealed assembly instead of a simple replaceable bulb, while halogen-equipped versions often use standard serviceable bulbs. Aftermarket LED conversions can also change beam pattern, brightness, and warning behavior, so compare the installed bulb and connector before purchasing. When possible, remove the old bulb and check the part number or base style first, especially for headlights, turn signals, and tail lamps where variations are most common.
FAQ
What bulb size does the 2020 Nissan Altima use for the low beam headlight?
The listed low beam bulb size for the 2020 Nissan Altima is H11 on versions that use a replaceable bulb. Some trims may have LED headlight assemblies instead, so confirm your installed setup before ordering.
What is the high beam bulb size on a 2020 Nissan Altima?
The chart shows 9005 for the high beam on halogen-equipped versions. If your Altima has LED headlights, the high beam may be integrated into the LED assembly rather than using a separate bulb.
Does the 2020 Altima use LED fog lights?
Yes, the front fog light position is listed as LED. On many LED setups, the light source may be built into the lamp assembly, so replacement may involve the full unit rather than a loose bulb.
What bulb does the daytime running light use?
The daytime running light bulb is listed as 9005 for the 2020 Nissan Altima. As with other front lighting, verify whether your vehicle has a serviceable bulb or an integrated LED module.
What size is the front turn signal bulb?
The front turn signal bulb is listed as 7444NA. This is a common dual-filament style used in some front lamp applications, but you should still confirm the socket and bulb already installed on your car.
What bulb is used for the rear turn signal?
The rear turn signal bulb is listed as 7440. Rear lamp designs can differ by trim and market, so checking the bulb in the housing is a good idea before buying replacements.
What are the brake light and outer tail light bulb sizes?
Both the brake light and the outer tail light bulb are listed as 7443R on the 2020 Altima. That makes it easier to match the correct bulb for the rear lamp assembly, but you should still verify the exact side and housing style.
What bulb size is used for the inner tail light?
The inner tail light bulb is listed as 2825R, and this position may not be present on every trim or lighting package. If your car has a different rear lamp design, check the installed bulb before ordering.
What bulb does the back-up light use?
The back-up light bulb is listed as 921. This is a common replacement bulb, but some lighting packages may use different lamp construction, so confirm the socket type on your Altima.
What interior bulbs are listed for the 2020 Nissan Altima?
The page includes the interior door light bulb as 194, the dome light bulb as DE3175, and the trunk or cargo area light as 158. These are helpful reference points when replacing cabin and cargo lighting.
Are the license plate and center high mount stop light bulbs LED?
Yes, both the license plate light and the center high mount stop light are listed as LED for this model year. In many cases, LED units are integrated and may not use a standard replaceable bulb.
How can I make sure I buy the right bulb for my Altima?
The best approach is to match the bulb location, check whether your car uses LED or halogen lighting, and compare the installed bulb or socket before purchase. Trim and package differences can change the fitment, so visual confirmation is especially important for headlights and rear lamps.
