Each strip of lights has arrows denoting the direction of “forward” “flow” for light patterns from that app that flow in a “forward” direction. Keep in mind the app will also offer “reverse” patterns. The arrows are helpful for orientating things during installation. For instance if you want “forward” flow patterns for your underglow kit to start at the front of your cart and flow strip to strip to the rear of the cart, arrange all the strips so that the arrows point toward the back of the cart. There is no right and wrong way of doing it of course. There are almost an equal number of “reverse” patterns and “forward” patterns. When installing wheel lights the arrows can help you make sure that the wheels all chase in the same direction (if that is what you prefer) or in opposing directions (if that is the look you are after).
