2018 Toyota 4Runner Headlight Bulb Size
Toyota kept the 2018 4Runner mechanically unchanged because there was nothing that needed fixing, and the market agreed: resale values remained among the highest in the SUV segment, fueled by legendary reliability and body-on-frame durability. The 2018 Toyota 4Runner headlight bulb size is H11 for the low beams, 9005 for the high beams, and H16 for the fog lights. This fitment covers every trim from the SR5 to the Limited and TRD Pro.
Searching for 2018 Toyota 4Runner LED headlights means you are ready to bring the one area where the 4Runner shows its age — lighting — into the modern era. A direct-fit LED kit from HID Nation eliminates the fading halogen output with a crisp white beam. Free shipping and a lifetime warranty come standard on every order.
Best LED and HID Kits for the 2018 Toyota 4Runner
LED kits for the 2018 4Runner plug into the factory H11 and 9005 connectors as a direct replacement. The driver unit is small enough to fit behind the headlight dust cap, and the change from halogen yellow to 6000K white is immediate. Whether you are navigating a trailhead access road at dusk or merging onto a dark highway, the visibility improvement is substantial. Plan on about 20 minutes for both sides.
HID xenon kits remain the choice for owners who prioritize maximum beam distance. The ballast-powered xenon arc generates a wide, deep pool of light that halogen cannot approach. Installation takes approximately 35 minutes, and the result is especially appreciated during long nighttime drives on open roads.
All HID Nation kits come with free shipping and a lifetime warranty, so you are protected for as long as this insanely durable truck stays in your garage.
Frequently Asked Questions
What headlight bulb size does the 2018 Toyota 4Runner require?
The 2018 Toyota 4Runner requires H11 bulbs for the low beams, 9005 bulbs for the high beams, and H16 bulbs for the fog lights. This is consistent across the SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, TRD Pro, and Limited trims.
Does the 2018 4Runner still use halogen headlights?
Most 2018 4Runner trims come with halogen projector headlights from the factory. Certain TRD Off-Road Premium and Limited configurations added LED headlights, but the majority of trucks on the road have halogen. If yours has halogen bulbs, an LED conversion kit is a direct plug-and-play upgrade that brings the output well beyond the factory level.
Why are 2018 4Runner resale values so high?
The 2018 4Runner commands strong resale values because of its body-on-frame construction, proven 4.0-liter V6, and reputation for lasting well past 200,000 miles. Investing in better headlights makes sense for a vehicle that will be on the road for years to come, and a lifetime-warranted LED kit from HID Nation ensures the lighting stays strong for the long haul.
Can I upgrade the fog lights to LED on the 2018 4Runner?
Absolutely. The 2018 4Runner uses H16 fog light bulbs, and LED replacements in the H16 size drop right in. Upgrading the fog lights alongside the headlights gives the truck a consistent white look and improves low-visibility driving conditions like rain, dust, and morning fog.
Is the 2018 4Runner headlight the same as the 2019?
Yes. The 2018 and 2019 Toyota 4Runner share the same fifth-generation platform and use identical H11 low beam, 9005 high beam, and H16 fog light sockets. An LED or HID kit purchased for the 2018 fits the 2019 without any changes, and vice versa.
