A few compatible replacement miniature fuse style light bulbs with their part number as are follows: TS-14V1CP, 6614F and 6641.

If you would like to have brighter vanity mirror lights that will also last much longer before burning out, install some 29mm long TS-14V1CP LED bulbs.

The only tool needed to access and replace the light bulbs is a small flat head screwdriver or a small plastic pry bar tool.

Flip down the sun visor to access the two vanity light housings.

To prevent from scratching the plastic surfaces, you can either cover the tip of your screwdriver with a thin micro fiber cloth or instead use a small plastic trim panel removal tool.

Gently insert the blade of the screwdriver in between the bottom edge of the translucent plastic lens cover and the light housing.

Pry out the bottom edge of the lens cover to release the retaining clip.

Do NOT pry at the top edge of the lens cover since there is a large plastic tab that could be broken.

Swing out the bottom edge of the lens cover and then slide the large tab at the top out of the light housing.

Set the lens cover aside in a safe place.

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.

Do NOT apply pressure to the glass center part of the old light bulb to prevent from having it shatter and send shards of glass flying into your face and eyes.

The OEM (original equipment manufacturer) light bulb in this 2020 Tacoma TRD Sport was marked as part number Toshiba TS-14V1CP9X.

If you would like to have brighter vanity mirror lights, install some compatible replacement TS-14V1CP LED light bulbs.

To test the new light bulb, flip open the mirror cover.

Tip - If you installed an LED bulb and it doesn't work, pull it out of 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.

First, re-insert the large tab into the top of the light housing.

Then swing down the bottom edge and push on it to gently pop in the retaining clip.

Double check that the lens cover is securely attached and flush at every edge with the sun visor.

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