Cateye EL135 and LD130 Light Set
You won't find more beam for your buck - or for the size of your lights - than on Cateye's user-friendly set. Perfect for city commutes (you'll want something brighter for unlit streets), they are an easy fit using thumb screws (no need for screwdrivers or irreversible cable ties) and will knock-out loads of light using energy efficient LEDs that will last up to 80 hours on a single set of AA (front) and AAA (rear) batteries.
