Show us your headlight[s] setup? Any Planet Bike fans?
I currently use  Planet Bike Super Spots mounted on my handlebars and  Sport Spot mounted below on a Topeak Bar Xtender. I bought a brand new 2007 Bianchi Bay City hybrid/fitness bike. I'm going to start using it for some light touring. I may have to reconfigure my lighting setup to clear a front rack with items on top. The mounting brackets hold up very well and don't loosen. I also like the fact that I can take the lights off and use as flashlights.
