GMC is a US motor company that has existed for over a century, and at that time, it has produced quite a lot of models. Among the newer models is the Terrain, an SUV that has been in production for around a decade. Regardless of model or production year, every car needs aa bulb upgrade sooner or later.

Replacing the bulbs on a GMC Terrain is a procedure that starts with identifying the sizes of the bulbs. Since the bulbs are different for most models, this article contains the bulb sizes for the GMS Terrain.

Is there a reason for replacing the bulbs on s GMC Terrain?

Even though this model has only been around since 2010, some owners decide to replace their bulbs. The most obvious one is a bulb that is no longer working. If the dome light is out, it may not be a problem, but if some of the exterior lights go out, then it is not very safe to drive the vehicle.

On the upgrade side of things, the Terrain may have LED bulbs on some of the newer models, but the older ones come with HID and halogen bulbs. With LED technology becoming more and more popular and people that want to be on top of the popularity game.

Is there an advantage for installing LED bulbs on a GMC Terrain?

LED bulbs have plenty of advantages over the halogen and HID bulbs that may be already installed.

A common problem that the older types of bulbs have is their longevity. Halogen is among the oldest types of bulbs with the least amount of rater working hours. HIDs can last almost double, while LEDs are rated for at least five times more than those.

Something that most not realize is the fact that certain parts of a car can affect the longevity of others. Bulbs get their power from the alternator, meaning that the more power the bulbs draw, the more stress on the alternator you will have. To reduce the stress, you can replace the existing bulbs with LEDs because their power requirement is lower than the other types of bulbs.

Replacing a headlight bulb on a GMC Terrain

To ensure that you do not short something out, disconnect the power leads from the vehicle’s battery.

Locate the circular cap on the underside of the wheel arch plastic. Unscrew the screws holding it into place and remove it. Insert your hand in the hole and locate the plastic cap covering the bulb. Rotate the cap counterclockwise and remove it. Do the same with the bulb holder with the plug and replace the bulb.

Is the entire headlight replaceable?

Yes. You can remove the entire headlight assembly and replace it with a new one. Unlike a bulb replacement, you can do this procedure from under the hood.

Every light that you can find on your car can be replaced.
