Parking Light Replacement on a 2026 GMC Terrain Denali 1.5L 4 Cyl. Turbo

This how-to video shows you how to change the parking light bulb in your 2026 GMC Terrain. The parking lights on a car are also known as position lights or clearance lights. The parking light symbol in the 2026 GMC Terrain dashboard is represented by two small semi-circles facing opposite directions. The parking light is typically orange in color and the parking light bulb may be the same bulb as the turn signal bulb in some Terrains. It is possible for the turn signal filament of the dual function parking light and turn signal bulb to burn out and for the parking light to continue to function properly. Replacing the parking light bulb will restore functionality of both your turn signal and parking light in your Terrain.

When changing the parking light in your Terrain, be careful not to touch the glass part of the new bulb with your finger as this will cause it to burn out quicker. We recommend using gloves or a piece of paper towel to limit the potential of touching the bulb.
