What headlight bulb does a 2020–2025 Toyota Highlander use?

LED (all trims; sealed unit, no user-replaceable bulb) for the low beam and LED (all trims) 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 2020–2025 Toyota Highlander take?

LED (where equipped).

Can you put LED bulbs in a 2020–2025 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.
