2020 Toyota Tundra Headlight Bulb Size
The 2020 Toyota Tundra represents the final evolution of the second-generation platform before the all-new third generation arrived for 2022. With the Trail Special Edition and the legendary "million mile Tundra" reputation behind it, this is a truck that owners buy once and keep for decades. The 2020 Toyota Tundra headlight bulb size is H11 for the low beams, 9005 for the high beams, and H16 for the fog lights. Halogen headlights come standard on the SR, while SR5 and above include upgraded lighting packages.
Tundra owners are not the type to trade in every few years. If your 2020 Tundra is going to be in the driveway for the next fifteen years, the factory halogen bulbs will need replacing long before the truck shows any signs of slowing down. Upgrading to 2020 Toyota Tundra LED headlights now means you get better visibility today and avoid the cycle of replacing dim halogen bulbs every year or two.
Best Headlight Upgrade for a Truck Built to Last
The 2020 Tundra shares its headlight architecture with the rest of the second-generation lineup, so every LED and HID kit designed for the 2014-2021 Tundra fits perfectly. LED kits slide into the H11 low beam and 9005 high beam sockets with nothing more than a twist. The 6000K white output is a stark improvement over halogen yellow, and the 50,000-plus hour rated lifespan means these bulbs can genuinely outlast the truck itself.
For owners who prioritize raw lumen density — think long-haul towing across empty stretches of interstate or ranch roads with zero ambient light — HID kits produce the most intense beam available. The trade-off is a compact ballast per side and about five extra minutes of installation time compared to LED. Both options transform night driving in the Tundra from manageable to genuinely comfortable.
Every HID Nation kit includes free shipping and a lifetime warranty with no expiration date. For a truck built to run forever, that kind of no-limits coverage makes sense.

Frequently Asked Questions
What headlight bulb does a 2020 Toyota Tundra use?
The 2020 Toyota Tundra uses H11 bulbs for the low beams, 9005 bulbs for the high beams, and H16 bulbs for the fog lights. This applies to all trims from the base SR through the TRD Pro, Platinum, and 1794 Edition.
Is the 2020 Tundra the last of the second generation?
The 2020 Tundra is part of the final run of the second-generation platform that debuted in 2007. Toyota continued this generation through 2021 before launching the fully redesigned third-generation Tundra for 2022. The second-gen Tundra's headlight architecture remained consistent throughout, so any LED or HID kit designed for the 2014-2021 model range fits the 2020 perfectly.
How long will LED headlights last in my 2020 Tundra?
Quality LED headlight bulbs are rated for 50,000 hours or more. At two hours of headlight use per day, that translates to over 60 years of service. Factory halogen bulbs typically last 500 to 1,000 hours before dimming noticeably. For a truck with the Tundra's reputation for longevity, LED bulbs are the only headlight option that can realistically last as long as the truck does. HID Nation's lifetime warranty provides additional peace of mind.
Can I match the fog lights to my new LED headlights on a 2020 Tundra?
Yes. The 2020 Tundra fog lights use H16 bulbs, and LED replacements in matching 6000K white are available. Upgrading all three positions — H11 low beam, 9005 high beam, and H16 fog — at the same time gives you a uniform white lighting appearance across the entire front end. The complete three-position install typically takes about 45 minutes to an hour.
Will LED headlights work with the 2020 Tundra Trail Special Edition?
Yes. The 2020 Tundra Trail Special Edition uses the same H11 low beam, 9005 high beam, and H16 fog light bulb sizes as every other 2020 Tundra trim. LED conversion kits install identically regardless of the edition or appearance package. The Trail Edition's rugged styling pairs well with the crisp white output of an LED headlight upgrade.
