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

  2. 2

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

  3. 3

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

  4. 4

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

  5. 5

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

  6. 6

    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.

  7. 7

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

Tips and warnings

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