Hi Ivan, thank you for reaching out. The answer varies depending on the factory headlights of your 2018-2021 Toyota Tundra. This product is incompatible with the 2018-2021 Toyota Tundra with factory LED headlights. This headlight set has different wiring compared to the factory LED headlight set. If your 2018-2021 Toyota Tundra has factory halogen headlights and you want to change the halogen bulbs to LED, you may do so, provided the LED bulb type is the same as the halogen bulbs. You may also need an LED CAN bus (Controller Area Network) decoder or load resistor to prevent the LED bulbs from flickering.
