We’ve already told you that GMC’s 2019 Sierra offers a host of new features such as the carbon fiber bed, MultiPro tailgate and Adaptive Ride Control. But one that we haven’t mentioned yet is Perimeter Lighting.
Officially called Perimeter Lighting System or Task Lighting, the feature illuminates the truck’s bed as well as the area around the truck, helping owners see in poorly-lit conditions such as on dark camping grounds, worksites, and even driveways.
The system on the 2019 Sierra uses eight different lights located in the following locations:
- Within the front section of the side mirrors, just outside the mirror caps
- Within the CHMSL cluster above the rear glass
- Within the rear corners of the bed
- The truck’s actual reverse lights
- Within the tailgate handle cluster
We have reason to believe that all five lights use LED technology.
On the 2019 Sierra, the Perimeter Lighting System is standard on the top three trim levels – SLT, AT4, and Denali. Trucks equipped with the system can be identified by the vertical LED strip on the front-facing part of the outside mirrors. In fact, these mirrors are central to the system’s functionality.
Assigned GM RPO Code DEZ, the mirrors also have a memory feature and are heated, power-adjustable, power-folding, and have puddle lamps.
Succeeds Cargo Box Lighting
The Side Perimeter Lighting feature on the 2019 Sierra succeeds the previous, K2 platform models’ LED cargo box lighting feature, which was a rather basic feature that only illuminated the cargo box. Perimeter/Task Lighting goes well beyond that by illuminating the cargo box as well as the area surrounding the truck.
Does The Silverado Get It Too?
Yes, the 2019 Silverado also gets the Perimeter Lighting System on the higher-end trims.
Both the Silverado and Sierra are all-new for the 2019 model year, with both trucks riding on the new GM T1 platform. The very first units of both pickup trucks began to arrive at dealerships in the second half of August.
