Correct the computer is using a transistor(s) as a switch, you would need to ID the transistor and see how much current it can sink.
Are the lights LEDs or light bulbs? You might get away with it if they are light bulbs and you change everything to LEDs and the total current draw of the LEDs is less than the original Light bulbs.
