NOTE: If you are replacing the turn signal assembly due to collision damage, it may be a good idea to replace the headlight assembly, as well. In this project, we will be removing the headlight, so it will never be easier to replace than right now!

Step 1: Open the vehicle's hood.

Step 2: Twist, lift, and remove the two mounting tabs that secure the headlight in place.

Step 3: Pull the headlight out and disconnect the wiring harnesses attached to the back of the assembly.

Step 4: Depress the retaining lever (located to the outer edge of the parking light), and pull the assembly through the front of the vehicle.

Step 5: Twist and remove the bulbs/sockets from the parking light assembly.

Step 6: Insert the bulbs/sockets into the new parking light, and mount it by engaging the retaining clip.

Insert the inner tab first, and then snap the assembly into place.

Step 7: Reconnect the wiring harnesses to the headlight assembly, and secure it by re-engaging the mounting tabs.
