I recently installed lights on my bicycle. Started out with Wal Mart specials and one just a tad better from the bike shop. Then I bought a Nite Rider Minewt 350 --what a light. It's the one. It drowns out the other 3. They make a 700 which is two of these with a splitter cable to run off one battery. I don't see a need for two of them. Has a rechargable battery. I don't like the battery mounting system--has a velcro strap. I find it better to leave the battery mounted all time and get an extension cord for the charger.

I have had good luck with Turbo Cat light systems, simple and well made. the S32 and TG10 is a very good set up.

Go to Geomangear.com, they have several nice lights. The moonshine is 900 lumens for about 100 bucks and they have Lupine a german made light that is awesome that is my pick. They even sell combo lights with bar mount lights 1600+ Lumens
