If your headlight bulb has burnt out, not only will you not be able to see as well at night, but you will prevent other drivers from being able to see you, and you may receive a ticket. Changing the headlight bulb in a Toyota Corolla can be done yourself and can save you money versus taking the car to a mechanic or dealership.

Reconnect the clip on the outside of the headlamp. Reconnect the power cable to the back of the headlight assembly.
