o to Amazon and they have a bunch of those lights including this one that comes with a bike mount, plus it comes with a tail light, and this one is cheaper: http://cgi.ebay.com/5w-LED-Bicycle-F...ht_6400wt_1136

CAUTION, these lights use 3 AAA batteries, look at the specs, 3 AAA bats won't last more then an hour on high, I have probably 1.5 watts in the Mars 4 running off of 2 AAA bats and it last about 13 hours on steady, and if you rechargeables you get even less run time.

Also some of those lights are only offered on E-Bay, just click on the pics and some will go to an e-bay site. Look at the going prices for this stuff, one light is a 1600 Lumen light with 1 minute left on the bidding and it's up to $24, another light is a 8 lumen light with 1 minute left and the bidding is up to 89 cents!!! Do people on e-bay know something we don't? I think they know their bad lights, and or the company won't stand behind their product like GeoMan and probably worse! that's why the bidding is so low. Here's one that's up to 95 cents with just 2 minutes left when I clicked on: http://cgi.ebay.com/5W-Bright-LED-Fl...ht_2103wt_1118
