For the 2016-2020 Lexus LX570, "plug and play" LED upgrades typically come in two forms: replacing just the bulbs (if compatible) or swapping the entire headlight assembly. However, note that due to the LX570's advanced factory lighting systems (like AFS), not all "plug and play" kits are truly effortless; some may require specific CANBUS decoders to prevent errors, and full assembly swaps often need professional installation to retain features.
