How do they look? I recently bought a self contained light kit from jc27 knowing that I had an incompatible perspex block with designs to either cut it down or build a new one from scratch. But I can't find any examples of what the block should look like. Just dremelling out the space for the CR2032 battery would leave me with an unsightly gouge when lit up. Does anyone have any pictures of a perspex block designed for self contained lights? I want to make it as neat as possible.
