All you need to do is commute nightly in an urban environment to realze that you are gonna die unless you put some more serius wattage on your bike.

$3.00 lights are great and have many uses and you sure get alot more than you used to. But as a primary bike light for a commuter they are inadequate

penny wise and pound foolish. thanks for the link it's been a while since I browsed their accesories. I do run one of their cheap blinkies as a backup.
