I have these Blackburn flea 2.0. These are bright as shit and people will notice you. The high beam will let you see a few feet in front of you and they are also rechargable. However, you'll have to charge them every 3 or 4 days as they go out pretty quickly. I go out on hour long night rides everyday and they last 5-6 hours on the medium intensity setting. The blinkers will blind the drivers so they're really good.

My brother has the Blackburn Voyager Click Light, as the one tonaros posted, and they are alright compared to the ones I have.

I use helmet mounted lights and then take my helmet with me after I lock my bike up. http://www.amazon.com/Blackburn-Front-Headlight-Light-Charger/dp/B00449IU6E/ are pretty good, and they clip right in to the helmets made by Bell, such as this one: http://www.amazon.com/Bell-Muni-Bicycle-Road-Helmet/dp/B00479TZWO/

If you're looking for some extra bright lights, you can get these instead (these are the ones that I own): http://www.amazon.com/Blackburn-2015-Super-Front-Light/dp/B00IT4ZN42/
