Increase nighttime and harsh condition visibility in your GMC Sierra 1500 with the genuine GMC fog light kit. Includes a pair of LED fog lights to not only aid in visibility, but also add a modern style to the front of your GMC truck. These lights are the same as the optional T3U (RPO U12) lights found on multiple Sierra models. Once installed, these fog lights must be programmed by a GM dealer. Does not fit models with task/perimeter lighting.
Note: Must be programmed by a dealer after installation in order for the BCM (Body Control Module) to recognize the lights.
Note: 2022 LTD model fitment requires RPO J21, the production year 2021. Will NOT work on refresh models.
Note: Will NOT work on 1WT (Work Truck) models.
Make sure your vehicle is equipped with task lighting. Refer to the photos below to check if your GMC Sierra has task lighting. You may also look in the Service Parts Identification (Silver in color) in the glove box/compartment. Make sure U12 is NOT listed.
