How to make a nice pair of halogen bicycle headlamps using only materials available at Home Depot…a 20 watt low beam and a 50 watt high beam with MR16 Halogen Spot bulbs. Note: Floods don’t give you enough range at speed and you want to get the bulbs that have a flat piece of glass at the front. Thanks Jake! Link.
