Ventura lighting set induction This lighting set from Ventura consists of two flashing lights with reflector. The red one is for the back of your bike and the white one is mounted on the front hub, so that you are clearly visible in the dark. Each light contains two clear and flashing LEDs. The lights are powered by induction, whereby the supplied magnets must be mounted on the spokes and by moving past each other, they generate electricity to keep the lights on.
