2017 Toyota 4Runner Headlight Bulb Size
Toyota added LED headlights to certain TRD Off-Road Premium configurations for 2017, acknowledging that serious off-road trucks need serious lighting, while the rest of the lineup continued with the proven halogen projector setup. The 2017 Toyota 4Runner headlight bulb size is H11 for the low beams, 9005 for the high beams, and H16 for the fog lights. This fitment is consistent from the SR5 through the TRD Pro and Limited trims.
Owners researching 2017 Toyota 4Runner LED headlights are typically looking to bring their halogen-equipped truck up to the same lighting level as the factory LED trims. An aftermarket LED conversion kit from HID Nation does exactly that with a simple plug-and-play installation. Every kit ships free and carries a lifetime warranty.
Best LED and HID Kits for the 2017 Toyota 4Runner
LED kits for the 2017 4Runner connect to the existing H11 and 9005 sockets with no wiring modifications. The integrated driver fits behind the headlight dust cap or mounts to the housing bracket, and the output switches from halogen yellow to a crisp 6000K white. Night driving visibility improves dramatically, whether you are on a highway on-ramp or a gravel forest road. Both sides install in under 25 minutes.
HID xenon kits are the go-to for drivers who need maximum beam throw on dark, open roads. A slim ballast per side powers the xenon arc, producing a dense column of light that reaches farther than LED. Installation runs about 35 minutes, but the illumination depth is ideal for the go-anywhere driving the 4Runner was built for.
HID Nation backs every kit with free shipping and a lifetime warranty, making better lighting one of the easiest upgrades you can add to this truck.
Frequently Asked Questions
What headlight bulb size does the 2017 Toyota 4Runner use?
The 2017 Toyota 4Runner 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 including the SR5, TRD Off-Road, TRD Off-Road Premium, TRD Pro, and Limited.
Did Toyota add factory LED headlights to the 2017 4Runner?
Toyota introduced LED headlights on select 2017 TRD Off-Road Premium models. Other trims continued with halogen projector headlights. If your 4Runner has halogen low beams, an aftermarket LED conversion kit brings the brightness and color temperature up to a level that rivals or exceeds the factory LED option.
Is the 2017 4Runner headlight bulb the same as the 2016 and 2018?
Yes. The 2016, 2017, and 2018 Toyota 4Runner all use the same H11 low beam, 9005 high beam, and H16 fog light bulbs. The fifth-generation platform remained unchanged across these years, so an LED or HID kit purchased for any one of them fits the others.
Will LED headlights handle the vibration of off-road driving in the 2017 4Runner?
LED bulbs are solid-state with no glass filament, so they handle vibration much better than halogen. This is a genuine advantage for 4Runner owners who take their trucks on rough terrain where jarring impacts are common. The lack of a delicate filament means the bulb is far less likely to fail from shock or vibration.
What fog light bulb does the 2017 Toyota 4Runner use?
The 2017 Toyota 4Runner uses H16 fog light bulbs. LED H16 replacements provide a wider, whiter beam spread near the ground that improves visibility in fog, dust, and rain. The swap takes about five minutes per side and requires no tools beyond what is needed for a standard bulb change.
