I just want to see the road at night very well. I ride home in the dark quite often. The deer here are numerous, but small. An impact, even a small one, will ruin your ride though. The lights on my Vstrom are among the best I've ever had. I would like to have at least that same degree of output from the Halogen unit on the GS. If the LED is light years ahead, it would be worth the bump to me. If not, I'll just get some axillary driving lights. TPMS matters not to me.
