Einleitung
In this headlight bulb upgrade and replacement guideline, I will upgrade the LED headlight for the 2019 Toyota Highlander. The primary purposes of this upgrade are to improve the headlight's brightness and increase the driver's night vision. The LED light provides more illumination, and clear white light can help the human eyes see more clearly and less eyestrain than the OEM headlight. It means the drivers will be more comfortable and safer when driving at night.
Before beginning this repair, turn off the car's ignition, place the car in park, and engage the parking brake.
