Some of our newer 2018+ F150's have the marker light located in a different location than the 2015 model used in the video.
To access the marker lights on the new models, please peel back the wheel well lining. Then find the side marker light which is now located towards the middle of the headlight unit.
This can be seen in the video below, which shows how to change out the marker light itself on 2018+ F150's.
Then connect your ground and power leads as shown in the main raptor grill light install video and you should be all set!
