This 2018 GMC Sierra Denali came to us all the way from Texas in need of custom LED safety lighting from Wicked Warnings. While this impressive SUV came to us already equipped with a few upfits, our team took it to the next level with custom design and installation. Check out the Wicked Warnings products we used in the 2018 GMC Sierra Denali emergency vehicle upfit. 

2018 GMC Sierra Denali: TIR-3

In the front fascia, we installed our exclusive TIR-3 LED lights in the headlight bezels in the color white. The TIR-3 LED lights have been installed sideways in order to provide increased visibility from the side for added warning. We did not place the TIR-3 inside the fog light, but next to it. The light actually reflects off the fog lamp inside the bezel giving off forward facing light as well.

2018 GMC Sierra Denali: LED HAW DUO

We installed our LED HAW DUOs in the cargo and rear reverse lights in white and synchronized in an X pattern. We also installed additional units brought to us by the client. The client-supplied LED is a white and blue strobe LED we placed by the license plate. Wicked Warnings offers similar products in our online store.

2018 GMC Sierra Denali: Rocker Switch

The LED safety lighting is controlled by our highly popular rocker switch, which we installed in the cabin under the left a/c vent. The placement of this switch is extremely convenient, and looks as if it came from the manufacturer. It is placed inside the 2018 GMC Sierra Denali where the driver can easily see it.
