In order to replace the high-beam bulbs, you first need to know where they are located.

To find the left high-beam bulb, look between the inside of the left headlight and the car's windshield wiper fluid container.

To find the right high-beam bulb, look between the inside of the right headlight and the car's battery.

As you are about to see, this guide shows the replacement process of the right bulb for a 2017 Toyota Tacoma. This means that the engine may not look exactly the same as your vehicle's engine. If that's the case, a good rule of thumb to find the bulb is to use the headlight as a reference point. The bulb will always be located behind the headlight.
