No specific thread, but we've had some discussion on lights here since our daylight is beginning to fade. Over on BikeJournal there's lots of talk about lights and it seems there's just no substitute for the big battery lights (10W halogen vs. LED). When I saw the Planet Bike 15W halogen on sale at Performance.com, with an online coupon for 20% off on $75 or more, I went for it and got the light for about $70 (sorry, I don't think this coupon is valid anymore!) This is hideously expensive for me but it was the only way my family would consider letting me keep riding as it got darker. By the end of this month it'll be full dark before I leave my building! I'm always interested to see what people have done to make themselves visible. Check out Newfsmith's pics on this thread http://forums.teamestrogen.com/showt...ghlight=lights
