2015 Toyota 4Runner Headlight Bulb Size
The 2015 model year was a landmark for the 4Runner because it debuted the TRD Pro, complete with Bilstein shocks, a heritage-inspired grille, and Inferno orange paint that made the off-road community take notice overnight. The 2015 Toyota 4Runner headlight bulb size is H11 for the low beams, 9005 for the high beams, and H16 for the fog lights. This applies to every trim from the base SR5 through the new TRD Pro.
Owners looking into 2015 Toyota 4Runner LED headlights often want lighting that keeps pace with the truck's trail capabilities. The factory halogen bulbs fade over time, leaving you with less visibility exactly when you need it most. HID Nation's plug-and-play LED kits restore and surpass the original output, with free shipping and a lifetime warranty on every order.
Best LED and HID Kits for the 2015 Toyota 4Runner
An LED kit for the 2015 4Runner plugs straight into the H11 and 9005 factory connectors. No wiring modifications, no adapter harnesses, and no housing changes. The upgrade moves your beam color from halogen yellow to a 6000K white that reveals trail obstacles, road signs, and wildlife much earlier. Most owners finish both headlights in about 20 minutes.
HID xenon kits push the beam farther down the road with higher total lumen output, which matters on unlit highways and remote forest service roads. Each bulb connects to a compact ballast that fits behind the headlight housing. The install takes roughly 30 to 40 minutes, but the depth of illumination makes it worthwhile for anyone logging serious after-dark miles.
All HID Nation kits ship free and come with a lifetime warranty, protecting your investment in better lighting for as long as you own the truck.
Frequently Asked Questions
What headlight bulb size does the 2015 Toyota 4Runner take?
The 2015 Toyota 4Runner takes H11 bulbs for the low beams, 9005 bulbs for the high beams, and H16 bulbs for the fog lights. All trims including the SR5, SR5 Premium, Trail, Limited, and TRD Pro share this same fitment.
Does the 2015 TRD Pro 4Runner have different headlight bulbs?
No. The 2015 TRD Pro uses the same H11 low beam, 9005 high beam, and H16 fog light bulbs as every other 2015 4Runner trim. The TRD Pro package adds off-road suspension and unique styling, but the headlight bulb sockets are identical across the lineup.
How do I install LED headlights on a 2015 Toyota 4Runner?
Open the hood and locate the headlight bulb access behind each housing. Twist the H11 retainer counterclockwise and remove the old halogen. Insert the LED bulb into the same socket, reconnect the wiring, and mount the slim driver unit behind the housing with the included bracket or zip tie. Repeat on the other side. The whole job takes roughly 20 minutes.
What fog light bulb fits the 2015 Toyota 4Runner?
The 2015 Toyota 4Runner uses H16 fog light bulbs. LED replacements in the H16 size install the same way as a standard fog light change and provide a wider, whiter spread of light close to the ground. This is helpful in rain, dust, and fog, conditions the 4Runner frequently encounters on and off the trail.
Are LED headlights durable enough for off-road use in the 2015 4Runner?
LED headlight bulbs have no fragile filament like halogen, which makes them more resistant to the vibration that comes with off-road driving. They also generate less heat and draw less power, reducing strain on the alternator during long trail runs. HID Nation backs every LED kit with a lifetime warranty, so replacements are covered even under demanding conditions.
