Which Toyota Highlander model years does this cover?

These headlight bulbs specifications apply to every Toyota Highlander built from 2014 through 2019 — the XU50 (3rd generation), mid-size 3-row crossover suv.

What headlight bulb does a 2014–2019 Toyota Highlander use?

H11 (halogen projector on most trims; some 2017–2019 Limited/Platinum have LED units with no serviceable bulb) for the low beam and 9005 (HB3) for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

What fog light bulb does a 2014–2019 Toyota Highlander take?

H11 (where equipped).

Can you put LED bulbs in a 2014–2019 Toyota Highlander?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
