(The 7th generation S650 Ford Mustang is supposed to be released in 2022 as a 2023 model year vehicle.)

Owners of other Ford and Lincoln vehicles such as the Fusion, Taurus, Escape, EcoSport, Flex, Expedition, Bronco, Ranger, Transit, F-150, C-Max, Fiesta, Focus, Edge, MKZ, Continental, Corsair, Nautilus, Aviator and Navigator may also find these DIY instructions to be helpful.

The compatible replacement sub miniature light bulb part number is 74 which are available from various manufacturers such as Sylvania, Philips, GE and Bosch.

If you would like to have brighter vanity mirror lights that will also last much longer before burning out, install some 74 LED bulbs.

(The "74" bulb was often used in older cars to light up the gauges, instrument cluster, gear selector and A/C controls. Most modern cars now often have LEDs to illuminate the gauge cluster.)

The tools needed to access and replace the vanity light bulbs include a flat head screwdriver or a plastic pry bar tool and a pair of needle nose pliers.

The first two steps are to lower the sun visor and then swing open the vanity mirror cover.

Insert the small flat head screwdriver in between the outer edge of the lens cover and the light housing.

Try to avoid using excessive force. The lens cover should pop out relatively easily.

Avoid placing the screwdriver near the mirror to prevent from scratching or cracking it.

If you have a small plastic automotive trim panel removal tool, I recommend using that instead of a metal screwdriver.

Set the lens cover aside in a safe place.

I covered the jaws of my needle nose pliers with blue painter's tape for some extra grip on the old light bulb.

Very gently use the needle nose pliers to pull the old light bulb straight out of the socket.

The old part was marked as a "12V2W" (12 volts, 2 watts) bulb.

Make sure it is fully seated in the socket.

(If you find that the 74 bulb is too large for the socket, you may need to buy the slightly smaller E74 European specification sub miniature light bulb.)

First, re-insert the two tabs on the outer edge into their slots.

Then gently snap in the inner edge of the lens cover back into place.

To test the new light bulbs, open and close the mirror cover.

You may need to press the "Unlock" button on the key fob to re-activate the exterior lights or switch the ignition on to the "Accessory" position.

Tip - If you installed an LED bulb and it doesn't work, try removing the bulb from the socket, rotate it 180 degrees and push it back into its socket. Some LED bulbs are "polarized" and will only work when the "+" positive and "-" negative electrical contacts are in the correct orientation. If the bulb still doesn't turn on, check your fuse box for a blown electrical fuse.
