2014 Corolla Tail Lights
Open Trunk Lid
Pry Out Pop Rivet
This automotive maintenance tutorial was specifically written to assist owners of the eleventh generation (2014, 2015, 2016, 2017 and 2018) Toyota Corolla in changing a burnt out brake, rear turn signal or reverse bulb in the tail light housings.

Owners of other Toyota, Lexus or Scion vehicles such as the Yaris, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

The replacement bulb part numbers are as follows: Brake # 7443, Rear Turn Signal 7440A or WY21W and Reverse # 921.

To access and replace the tail light bulbs, you'll need a flathead screwdriver, a plastic pop rivet removal tool or a pair of needle nose pliers.
