My 2011 Suzuki V-Strom had twin headlights which were probably the best I had ever experienced on a motorcycle to that point. Both light were on whether low beam or high beam was selected. My ATAS has one light on with high beam or low beam and the other only lights up when high beam is selected. I prefer both lights lit at all times but will live with one on low beam and two on high beam. I have noticed a lot of other bikes with this combination on the street in the last few years. Is this a legislative thing or a marketing thing?
