Abstract: A method of lighting a panel made of resin absorbing material is taught along with a lay up for carrying out the method. The method involves fixing a light generating means, preferably fiber optics, within a layer of the lay up which may be resin absorbing or non resin absorbing, rigid, flexible or semi-rigid in different embodiments. The method involves flowing resin from an inlet opening into a sealed mold which may be as little as a shaping layer and a vacuum bag. The lay up is comprised of at least one top layer of absorbent or reinforcing material which defines a passage or hole from the inlet opening to a non-absorbent layer which non-absorbent layer lies above at least one bottom layer of reinforcing material. At least one of these layers contains the light means, which are preferably fiber optic fibers. The fibers where necessary are protected in a tube prior to filling the lay up with resin at the point of entry into the mold to protect them.
