RETROFIT ILLUMINATION SYSTEM: Interplex Solar's newest product to join its range of effective solar powered signs and warning systems is the RETROFIT ILLUMINATION SYSTEM (R.I.S.). The R.I.S. is a self-contained system which can be easily attached to any existing traffic sign or other commercial sign. It is no longer necessary to discard existing signs and infrastructure. Interplex Solar's R.I.S. converts any existing sign to solar power within minutes.
No special training or equipment is needed for the installation of these kits. They are easily attached with a minimum of time and effort.
