This automotive maintenance tutorial was specifically written to assist owners of the first generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GMC Terrain in changing a burnt out vanity mirror light bulb in the sun visor or upgrading both bulbs to brighter LED units.

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Acadia, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

The OEM light bulb was part number TS-14V1.5CP54.

A few compatible replacement miniature "fuse" type light bulbs are as follows: TS-14V1CP, ACDelco 13502343, 6614F, TS-14V1.5CP and Eiko 40842 - 6614F.

Gently Pry Out Old Bulb

To prevent from scratching the plastic surfaces, you may choose to cover the tip of your screwdriver with a thin micro fiber cloth.

Insert the blade of the small flathead screwdriver in between the edge of the lens cover and the light housing.

Gently pry out the lens cover and set it aside in a safe place.

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

Either pull out the old bulb with your fingers or carefully pry it out at one of the metal end caps with the flathead screwdriver.

Do not apply pressure to the glass part of the bulb to prevent from having it shatter and send glass shards in to your face or eyes.
