A vehicle marker light assembly including a plurality of preferably serially-connected, programmable light unit modules, each module having a microcontroller and a plurality of LEDs, which have a dual function as a marker light and, alternatively, as an emergency or warning light. In a preferred embodiment, microcontrollers of adjacent modules are programmed to communicate instructions to the light unit modules, causing the LEDs to flash in one or more predetermined patterns or sequences. In this embodiment, the light unit modules are configured in longitudinal strips or other desired forms, and are designed to operate on low amounts of current. In another preferred embodiment, a controller providing command instructions to the light unit modules causes flashing of the marker lights in the predetermined patterns or sequences. Preferably, the light unit modules include electrical circuits to provide protection against unwanted electrical noise and transients, and fail-safe circuits to revert a failed light unit module to a marker-only mode and to allow electrical communication to pass through to an adjacent light unit module.

The light assembly of claim 11, wherein the controller communicates with the light unit modules through a wireless electrical communication.13. The light assembly of claim 1, further comprising a connector allowing the electrical communication between the light unit modules, the connector comprising at least three wires.14. The light assembly of claim 1, wherein each light unit module draws about 100 milliamps or less of current.15. The light assembly of claim 1, wherein the light unit modules comprise a UV stable lens.16. The light assembly of claim 1, wherein the light unit modules comprise molded optics.17. The light assembly of claim 1, wherein the light unit modules are waterproof.18. The light assembly of claim 1, wherein each light unit module further comprises one or more electrical circuits to provide protection against unwanted electrical noise and transients.19. The light assembly of claim 1, wherein each light unit module further comprises one or more fail-safe circuits to revert a failed light unit module to a marker-only mode and to allow electrical communication to pass through to an adjacent light unit module.20. A light assembly serving a dual role as a marker light, and alternatively as an emergency or warning light for a vehicle, comprising:a plurality of light unit modules, each of the light unit modules comprising a microcontroller and a plurality of LEDs; wherein the light unit modules are serially connected to a vehicle power source and are selectively programmable, allowing a vehicle operator to cause the light unit modules to flash in predetermined patterns or sequences functioning as marker lights, and alternatively as emergency or warning lights, at the operator's control and discretion.
