A lamp driver card to control lighting of a lamp load located on a wayside of a railway system is provided. The lamp driver card comprises a light source controller module including at least one channel having a semiconductor switch or a relay to receive power on a copper cable sized at a selected gauge size from a power source to turn ON or OFF the lamp load. The light source controller module is configured to support a multi-voltage rating range operation extended from a limited voltage to an extended operating voltage and a current rating to light the lamp load such that the light source controller module is compatible with relatively higher DC/AC voltages. The copper cable is sized at the selected gauge size of a first size to a second size based on a selected voltage rating of a first voltage system or a second multi-voltage ranges system.
