The lights arrived much quicker than most things I order and have delivered overseas. Install was a snap (no pun intended) and they look great and are very bright. You only need to run your hazard lights for a few minutes so the bike syncs up, otherwise you notice the blinker runs quicker. Duplicate review for the front running lights since I ordered them together. I do believe these saved me from being rear ended soon after I got them. Traffic on the autobahn suddenly stopped in front of me but I didn't get hit.
