It is this gear bed which actuates the light apparatus. It is an escarpment mechanism. This is what keeps the lights rotating at their assigned frequency. The lightkeeper must also be a bit of a tinker, in order to keep the clock running on time. Each lightstation is assigned an individual flash, which is recorded in the International Lighthouse Lists book.
