The HM RGB 1 BK enhances your experience with multicolor LED lighting that can be changed to fit your mood or craft. Is composed by an RGB CONTROLLER specifically developed for HMX LD option models including a radio frequency remote control with a wide
array of functionalities ranging from the selection of the color better matching your boat/ATV/motorcycle to the creation of a lighting game reacting to music tempo.
Built-in RGB led lighting creates sophisticated atmosphere, adding tons of class to your vessel.
The protection grade IP65 for speakers define all the Hertz Marine products as totally protected against water jets of different entities, making them highly performant in the marine environment.
According to the severe ASTM-D4329 standards for UV resistance, all the materials used for Hertz Marine products are designed to face long time exposition to UV radiations while cruising on the open sea.
To satisfy the standards required by ASTM-B117, Hertz Marine products are tested with massive salt fog spray to ensure a complete resistance to corrosion, typical of this atmospheric agent.
