The Planet Bike Beamer 1 and Blinky 3 light set is a great way to get good quality front and rear lights for not a lot of money.  The Beamer 1 is brighter and more focused that it used to be, so you get lots of light where you want and need it.  The Blinky 3 has three super-bright LEDs and a built in reflector so you are sure to be seen.
