I bought these for my Tiger because the stock lights are crap
http://www.twistedthrottle.com/trade/productview/6158/Easy to install and very bright. They can be wired into the bike lights to run hi and low or run on their own switch and are on hi all the time. They also come with 2 pairs of lenses. Beam and flood.
I've only had them for a couple months but the quality seems good and I've had no problems with them.
