I have a light bar for an 1100GS that I'd be willing to sell, if you're interested I can post pics.
Regarding lights, I highly recommend the Piaa LP530 leds for $191 on Amazon (less than the Advmonster Chinese lights), and they come with a harness that includes a waterproof switch as well as a 2 year warranty. http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER
These are the same lights that Yamaha now sells as an OEM accessory for the Super Tenere. Very high quality and great output with a nicely focused beam that won't annoy oncoming traffic.
But if you like the Chinese lights, round up a few friends for a group buy and you can get them for $50 apiece on Alibaba.
