This automotive maintenance tutorial was specifically written to assist owners of the third generation (2014, 2015, 2016, 2017, 2018 and maybe also the 2019 and 2020 model years) Toyota Highlander SUV in changing a burnt out low beam, high beam, front turn signal or side marker light bulb in the headlight housings.

Owners of other Toyota, Lexus and Scion vehicles such as the 4Runner, Avalon, 86, C-HR, Camry, Corolla, iM, Land Cruiser, Mirai, Prius, RAV4, Sequoia, Sienna, Tacoma, Tundra, Yaris, FR-S, xB,  xD, tC, xA, CT 200h, ES 250, ES 300, ES 330, ES 350, IS 250, IS 350, RX 300, GS 250, NX 300 and RX 350.

The compatible replacement light bulb part numbers are as follows: Low Beam # H11, High Beam # 9005, Front Turn Signal # 7444NA and Front Side Marker # 2825 (or W5W).

No tools are needed to access and replace the low beam or high beam bulbs. To change the front turn signal or side marker, you'll need a small flathead screwdriver or a small plastic pry bar tool.

1/4 Turn Counterclockwise
The first two steps are to open the hood and then move to the side of the SUV with the burnt out headlight bulb.

The low beam light is located near the middle of the headlight assembly. The lens resembles a "robot eye", in my opinion.

Reach in behind the headlight housing and locate the round grey plastic dust cap.

Rotate the dust cover 1/4 turn in the counterclockwise direction before pulling it straight out of the housing.

Set the dust cap aside in a safe place.

Rotate the base of the old low beam bulb 1/4 turn in the counterclockwise direction before pulling it straight out of the housing.
