A system for illuminating a bicycle having a frame comprising a plurality of tubular frame members wherein each frame member has a plurality of orifices. The orifices allow light rays to pass from inside each tubular frame member to outside each tubular frame member. Bulbs for emitting light are adapted to fit inside the tubular frame members and are conductively coupled to a power source. The power source is sized such that the power source fits inside a vertically situated tubular frame member. A planar platform, having a length in one direction that is less than the inside cross sectional diameter of the vertically aligned tubular frame member, is sized so that the platform fits inside the vertical tubular frame member. The platform supports the power source and is positioned such that the power source can be installed and removed by a user.
