2020 EcoSport Mirror
Gently Release Clip
Black Retaining Clip
This automotive maintenance tutorial was specifically written to assist owners of the second generation 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020 and 2021 Ford EcoSport compact SUV in changing a burnt out side view mirror turn signal light bulb (also known as the side marker, indicator or "blinker").

Owners of other Ford or Lincoln vehicles such as the Fiesta, B-Max, Escape, Edge, Bronco Sport, Explorer, Expedition, Transit, Focus, Mondeo, S-Max, Puma, Kuga, Endura, Everest, Ka, Figo, Endeavour, Aviator, Corsair, Nautilus and Navigator may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) miniature wedge base light bulb part number is WY5W.

If you would like to have brighter side view mirror turn signal light bulbs, install some WY5W LED bulbs.

If you have trouble finding the WY5W bulbs, it may be possible to use other miniature wedge base light bulbs that are "natural amber" colored such as the 194NA or 168NA.

The tools needed to complete this procedure include a flat head screwdriver and a plastic pry bar tool.

Attention: If you live in a cold climate, I highly recommend moving the car into a heated garage or wait for a warm day before attempting to complete this procedure. The plastic parts may be brittle and much more likely to break when they are cold. I sometimes place a space heater near the vehicle when detaching plastic door panels or removing tail light housings to help make the plastic more flexible and less likely to crack. Avoid placing a space heater or hair dryer too close to the plastic parts to avoid melting them.

Please proceed with caution and at your own risk!

To avoid scratching the plastic parts, you can either cover the tip of your screwdriver with a thin micro fiber cloth or instead use a plastic pry bar tool.

Very carefully insert the blade of the small flat head screwdriver in between the front inner edge of the light housing and the mirror housing.

There is a black plastic retaining clip that secures the front edge in place.

Gently pry out the front retaining clip. Please be patient and take your time. The plastic clip should pop out relatively easily.


Pry Out Rear Top Tab
Pry Out Rear Edge Tab
Rear Tab Released
Then move to the rear outer edge of the light housing.

There is a small black plastic tab at the top of the light housing near the rear edge.

Plus another small black plastic tab on the rear outer edge of the housing.

Insert the small flat head screwdriver in between the light assembly and the mirror housing.

Very gently pry out the plastic tabs. Try to avoid using excessive force to prevent from cracking the parts.

The curved body color painted mirror housing might pop apart from the black plastic frame. Don't worry, it can be re-assembled later on.

Releasing Rear Top Tab
Rotate Counterclockwise
Light Housing Removed
Once the light housing has been released, carefully rotate it in the counterclockwise direction to detach it from the mirror assembly.

The rubber bulb socket is only held in place by friction.

The bulb socket might pop out from the housing as you rotate it in the counterclockwise direction.

Demonstrating Again
Rotate Counterclockwise
Light Housing Detached
If you have trouble removing the light housing from the mirror assembly, you can try rotating the housing in the clockwise direction instead of the counterclockwise direction.
Pull Out Bulb Socket
Empty Bulb Housing
Pull Out Old Light Bulb
If the bulb socket doesn't pop out by itself, gently pull the socket straight out of the housing.

It is only held in place by friction due to the ribs on the rubber socket.

If the old light bulb was recently turned on, be careful when you remove it. The bulb might still be hot enough to burn your fingers.

Pull the old light bulb straight out of the socket.

If you have difficulty removing the bulb due to sand, corrosion (rust) or debris, try gently wiggling it back and forth while pulling it straight out.

Push In New Light Bulb
Test New Light Bulb
Rubber Bulb Socket

Push a new amber colored number WY5W light bulb straight into the socket.

If you would like to have brighter side view mirror turn signal lights that will also last much longer before burning out like the traditional incandescent bulbs, install some compatible replacement WY5W LED units.

Be sure to test the new light bulb before you re-insert the light housing. To test the new bulb, activate the hazard signals.

Tip - If you installed an LED bulb and it doesn't work, remove it from the socket, rotate it 180 degrees and push it back into the socket. Some LED bulbs are "polarized" and will only work when the "+" positive and "-" negative electrical contacts are in the correct orientation.

Once you are certain that new bulb is securely installed in the socket and working properly, you can move on to the next steps.

Push Socket Into Housing
Re-Insert Light Housing
Rear Outer Plastic Tab
Push the rubber socket straight into the light housing.

Make sure the socket is fully seated in place.

Carefully line up the two plastic tabs on the rear outer edge of the light housing with the opening in the mirror assembly.

Gently pop the rear outer plastic tab into its slot.

Slide the tab at the top of the light housing near the rear edge back into place.

Slide Tab Into Slot
Re-Insert Rear Top Tab
Retaining Clip Front Edge
Avoid using excessive force to prevent from breaking the plastic tabs.

Swing the front inner edge of the light housing towards the mirror assembly.

Gently pop in the front retaining clip.

You might hear or feel the retaining clip "click" securely into place.

Gently Pop In Plastic Clip
Light Housing Secured
Gap Between Panels
Make sure the light housing is securely in place.

If you popped apart the body color painted mirror housing and the black plastic mirror frame, carefully line them up.

Snap Together Panels
Double Check Installation
New Light Bulb Installed
Gently snap the two pieces back together.

The body color painted plastic mirror housing should be flush with the black plastic frame that surrounds the mirror.

To test the new light bulb again, activate the hazard signals.

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