Bike Light Racks are designed to create additional mount points for elastic band-style bike lights. Most people attach these lights directly to seat posts, and other parts of their frame. While this might work in the short term, these placements are ultimately not secure and can end up destroying the elastic band. Bike Light Racks are designed to enhance your experience by protecting your light and making it more prominent. We’ve heard from many customers that a better system is needed, and this is our solution. Bike Light Rack #1 is compatible with the most common bicycle rack accessory tab. It is secured with four 6 mm zip ties.
