The compatible replacement light bulb part number is 7440NA (also known as 7440A or WY21W).

If you would like to have brighter front turn signals, install some 7440NA LED bulbs.

The tools needed to complete this procedure include a Phillips head screwdriver, a 10mm socket and a 1/4" or 3/8" drive ratchet.

To access the turn signal bulb socket on the underside of the housing, you'll have to fully remove it from the engine bay and detach it from the front bumper cover.

(If you need to change the low beam or high beam headlight bulbs, please take a look at my DIY tutorial for the procedure at the following link: 2015-2019 Ford Edge Headlight Bulbs Replacement Guide.)

Locate the small black plastic screw near the rear outer edge of the housing.

Loosen the plastic screw by turning it in the counterclockwise direction with a Phillips head screwdriver.

Once the screw has been released, you can pry out the base of the plastic fastener with your finger nail or use a plastic pry bar tool.

Then remove the black metal bolt near the inner edge of the housing by turning it in the counterclockwise direction with a 10mm socket and a 1/4" or 3/8" drive ratchet.

(The inner bolt is longer than the outer bolt.)

Set the bolt aside in a safe place.

(The outer bolt is slightly shorter than the inner bolt.)

Set the bolt aside in a safe place.

To not mix up the two bolts, I recommend placing the outer bolt on the plastic cowl near the windshield on the outer edge and place the longer inner bolt closer to the middle of the cowl so that you can easily remember their positions.

Carefully lift the headlight housing up and out of the engine bay.

If you have trouble removing the headlight, you may need to gently wiggle the housing to release it from the front bumper cover.

The headlight assembly should pop out relatively easily.

Turn over the housing to access the round black plastic front turn signal light bulb socket located on the underside.

Carefully pull the old light bulb straight out of the socket.

If you have trouble removing a stuck or stubborn light bulb, put on some rubber gloves and carefully wiggle the bulb back and forth while pulling it straight out.

Try to avoid using excessive pressure on the old bulb.

(I once had an old bulb pop in between my fingers and cause a few cuts.)

Push a new amber colored number 7440NA light bulb straight into the socket.

If you would like to have brighter front turn signal lights that will also last a lot longer, install some compatible replacement 7440NA LED bulbs.

If you installed an LED bulb, I recommend testing it before you re-attach the headlight housing.

If the LED bulb doesn't work, try removing it from the socket, rotating it 180 degrees and then pushing it back into place.

Some LED bulbs are polarized and will only work when the "+" positive and "-" negative electrical contacts are in the correct orientation.

To replace the headlight housing, turn it back over and line up the headlight with the opening in the engine bay.

Lower it down on to the front bumper cover.

Try to avoid scratching the painted surfaces or the plastic headlight lens cover.

Push on the headlight until it is fully seated.

Rotate it a few turns by hand in the clockwise direction to prevent it from becoming cross threaded.

Tighten the bolt in the clockwise direction with the 10mm socket and a ratchet until it is snug.

Avoid over tightening the bolt to prevent from cracking the plastic.

Make sure the black plastic screw is in the up and fully released position.

Push the plastic fastener into the small opening at the outer edge of the housing.

Either use the Phillips head screwdriver to tighten the plastic screw or just gently pop it down with your finger.

Tighten it in the clockwise direction with the 10mm socket and ratchet until it is snug.

To test the new turn signal light bulb, activate the hazard signals.

Be sure to write down the bulb change in your vehicle's service records.
