Abstract
Programmable light assemblies that may function in various operating modes, such as to function as marker lights and/or emergency lights, or have other functions, are disclosed. The protocol and architecture of the light assemblies enables the associated light fixtures to provide a constant current output despite the presence of substantially large voltage ranges, and even when submerged in water. Alternative embodiments of the programmable light assemblies of the invention provide many other features as described herein.
