How to Replace the Front Signal Lights in a Toyota Corolla

If one of your front signal lights isn't working, folks driving in front of you won't know when you're turning. To decrease the chances of a collision, replace the signal light bulbs in your Toyota Corolla as soon as they burn out.

Shut the Corolla's engine off and engage the emergency brake for added safety. Also, make sure its headlights are switched off.

Open the hood using the primary and auxiliary hood release latches.

Use a Phillips screwdriver to remove the signal light assembly screw. This step only applies to Corolla models made between 2000 and 2002.

Locate the turn signal bulb socket on the inside of the engine compartment. The socket is right behind the signal lens cover.

Turn the signal bulb socket counter-clockwise to remove it from the assembly.

Pull the old bulb straight out of the socket and replace it with the new bulb. Dispose of the old bulb immediately to prevent it from becoming a hazard.

Test the new bulb to make sure it works before replacing the assembly and closing the hood.

Tip

Check Section 7-3 of your Corolla Owner's Manual if you don't know exactly which bulb to replace. Place the assembly screw in your pocket so you can find it when reassembling the light.

Warning

Don't touch the bulb socket unless you're sure your car's electrical systems are turned off.
