Lite Magic developed the Lite-Magic Underwater LED’s to withstand the strenuous underwater forces while attached to the transom of boats. This product was tested for a period of 1 1/2 years to ensure they are 100% water-proof. Many revisions were made to the prototypes. Finally, Lite-Magic was satisfied with the finished product that we are now selling to you. Due to the custom made LED strip versatility and durability, they are now being used in many applications in addition to boating.
