It’s that time of year again…time to bust out the headlight for a midweek-after-work-night ride! But, in order to have a fun and safe nighttime mountain bike adventure you need one critical piece of equipment…a bright light to adorn your helmet and illuminate the trail ahead. The only dilemma is, a good light system can run between $200-$300 bucks. I don’t know about the rest of you, but that’s a little rich for my blood. That’s why last year I decided to take the MacGyver approach and build my own Link.
