I have the GTS covers and have had two of them come off. I found the last one that came off so I still have 3.The thing is I don't want to get a new set (again) if they keep coming off. I have some 3M tape that I could use to hold them on but wanted to see if anyone has had this happen to them and what they did to solve the porblem. I don't know if I want to put the 3M right on the light. I was thinking maybe on the side of the cover and the inside of the fog frame?
