The latest technological advance in signal back plates is here, the Korman Signs LIGHTHAWK Series. They are made from ALPOLIC 350, a proven lightweight aluminum composite material, and 3M Diamond Grade Cubed (DG3) state-of-the-art reflective sheeting to produce a twelve year finished product. No longer do you have to worry about fading, cracking, & peeling failures. The LIGHTHAWK brand back plate is manufactured and made in the USA by Korman Signs, Inc. and can be fabricated to fit any signal head assembly.

A number of studies have confirmed the safety value of reflectorized signal back plates. The LIGHTHAWK ALPOLIC 350 Back Plates are an innovative and more effective approach to fulfilling the goal of improving intersection safety and reducing accidents. The weight to structural strength ratio of the ALPOLIC 350 and the high performance of the 3M reflective sheeting is unmatched and virtually prolongs the need of maintenance for the life of the signal light assembly itself.
