A method and apparatus for an adaptable vehicle light fixture is provided to activate varying light distribution patterns based upon preconfigured operation of trigger and/or power wires. One or more trigger and/or power wires connected to one or more vehicle light fixtures are preconfigured through wired and/or wireless programming to generate specified light distribution patterns that are responsive to the preconfigurations during manual operation. Wireless preconfiguration includes the use of a handheld magnetic device or smartphone. Wired preconfiguration includes the use of a vehicle-based controller area network (CAN) bus. Any preconfigured operation may be changed at any time by the user by programmably changing the preconfiguration.

A technology for configuring a lifestyle LED light with a tunable light color temperature is disclosed. The technology of tuning the light color temperature is made possible by blending two LED loads emitting light with different color temperatures thru a light diffuser with an arrangement that a first electric power delivered to a first LED load emitting light with a low color temperature and a second electric power delivered to a second LED load emitting light with a high color temperature are reversely and complementarily adjusted for tuning a diffused light color temperature such that a total light intensity generated by the LED light is kept essentially unchanged.

A light fixture controller is configured for controlling the color temperature and intensity of a light fixture that includes at least two LED groups. Each LED group includes multiple LEDs configured to produce light at certain color temperatures. The light fixture controller receives a color temperature setting and an intensity setting for the light fixture and generates control signals based on these settings. A first control signal only turns on the first LED group for a first duration of a cycle and a second control signal only turns on the second LED group for a second duration of the cycle. The ratio between the first and second duration is determined based on the color temperature setting. The control signal further includes a dimming control signal for controlling a current flowing through the LED groups based on the intensity setting for the light fixture.

A high voltage controller contains: a casing and a wire receiving orifice defined on a predetermined position of the casing and configured to receive a preferred wire and to connect with a predetermined light-emitting diode (LED) light source. The casing further includes an electric circuit board accommodated therein, and the electric current board includes a wave filter, a rectifier, an inverter which are arranged from a voltage input end to a voltage output end of the electric circuit board, such that the wave filter and the rectifier rectify electric currents, and an alternating current (AC) voltage is rectified into a direct current (DC) voltage. The inverter includes at least one transistor arranged in a matrix so as to invert into the AC voltage, and the AC voltage is outputted, hence the AC voltage and the DC voltage are transformed repeatedly to obtain no-shaking lights.
