How to Replace the Front Signal Lights in a Mercury Cougar

by Contributor

When one of the front signal lights on your Mercury Cougar burns out, be sure to replace it immediately to avoid causing an accident on the road. Once you've ordered the correct replacement bulb, you can install it easily in just a few minutes. These instructions don't apply to Cougar models made before 1999.

Step 1

Turn off your Cougar's engine and set the headlamp switch to "OFF." Open the hood using the primary and auxiliary hood release latches.

Step 2

Remove the center cover and the screws attached to the radiator grille. Pull the radiator grille out of the engine compartment and set it on the ground.

Step 3

Use a T30 Torx screwdriver to remove the two primary retaining screws from the headlamp assembly. Make a note of each screw's original location--they're not interchangeable, so you'll need to put them back in the right slot to reassemble the light.

Step 4

Draw the headlamp assembly away from the car and then disconnect the electrical wiring connector.

Step 5

Find the bulb socket that contains the broken signal bulb. Then, turn the bulb socket counter-clockwise to remove it from the assembly.

Step 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.

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