An automobile circuit includes a power source, a temperature sensor outputting temperature measurement data, a voltage sensor outputting system voltage measurement data, a voltage adjusting module configured to receive the temperature measurement data and the voltage measurement data, and responsive thereto, to output a pulse width modulation signal, a switch that is electrically coupled to the power source and to the voltage adjusting module, the switch being operable to receive the pulse width modulating signal and thereby regulate a duty cycle for voltage from the power source, and a lighting component coupled to receive the voltage from the switch.
