I am not sure what happened but the Light Network stopped forming. I have the Bontrager Ion 200RT/Flare RT lights. I also have the Varia RTL 515. The Edge 530 would recognize the radar if I manually turned on Varia, but not the taillight or the Bontrager lights. I tried several of the suggestions in the forum for fixing the problem but none of them worked. A factory reset on the Bontrager lights solved the problem!
