2019 Nissan Altima Headlight Bulb Size
The 2019 Nissan Altima marked a ground-up redesign as the sixth generation, bringing a world-first Variable Compression Turbo engine, available all-wheel drive for the first time in Altima history, and ProPilot Assist driver aids on SV trims and above. The 2019 Nissan Altima headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights. Even with the new platform's striking styling, adding 2019 Nissan Altima LED headlights to the base S trim is the quickest way to bring its lighting up to the standard set by the rest of the car's premium-leaning design.
The sixth-gen Altima looks sharp from the factory, and LED headlights complete the picture. On halogen-equipped trims, the upgrade eliminates the one visual element that still looks dated.
Upgrading the 2019 Altima's Headlights to LED or HID
On the redesigned 2019 Altima, LED conversion kits slot into the H11 low beam socket without any trimming or rewiring. The result is a 6000K white beam that matches the car's modern design language. LED bulbs produce less heat than halogen, protecting the new-gen housing lenses. Installation takes most owners roughly 15 minutes per side.
HID kits remain relevant for drivers who want the maximum throw distance on dark back roads. The ballast-and-bulb combination generates a dense, penetrating beam. Budget about 40 minutes for the full install including ballast mounting.
HID Nation covers every kit with a lifetime warranty and free shipping. Whether you choose LED or HID, the purchase is risk-free.
Frequently Asked Questions
What bulb size does the 2019 Nissan Altima headlight use?
The 2019 Nissan Altima uses H11 bulbs for the low beams, 9005 bulbs for the high beams, and H11 bulbs for the fog lights. The base S trim comes with halogen headlights, while SV and higher trims may include factory LED headlights depending on the package.
Does the AWD version of the 2019 Altima use different headlight bulbs?
No. The 2019 Altima AWD models use the exact same H11 low beam, 9005 high beam, and H11 fog light bulbs as the front-wheel-drive versions. The AWD system affects the drivetrain only and has no bearing on headlight fitment or electrical compatibility with LED kits.
Will LED headlights interfere with ProPilot Assist on the 2019 Altima?
LED headlight bulbs do not affect ProPilot Assist or any of the Nissan Intelligent Mobility features on the 2019 Altima. The forward-facing camera and radar sensors operate independently of the headlight bulb type. You can upgrade to LED without impacting lane-keeping, adaptive cruise, or automatic emergency braking.
My 2019 Altima already has factory LED headlights. Can I still upgrade?
If your 2019 Altima came with factory LED headlights from the SV or higher trim, the low beam is an integrated LED module rather than a replaceable bulb. Aftermarket LED conversion kits apply specifically to the halogen-equipped S trim. If you have factory LEDs, you may still upgrade the fog lights to a matching white LED for a consistent front-end appearance.
How does the 2019 Altima's VC-Turbo engine relate to headlight upgrades?
The Variable Compression Turbo engine and the headlight circuit are entirely separate. LED bulbs actually consume less power than halogen, which marginally reduces alternator load. There is no interaction between the engine management system and your choice of headlight bulb on the 2019 Altima.
