You can use a Power Mosfet to drive the light (I am taking for granted it is a DC Voltage the one that turns the light on), the only current a Mosfet demand is only to charge its input capacitance this way you will not damage your board. Configuration is so simple, signal goes at Mosfet Gate, set the load(light) between V+ and Mosfet Source and connect Mosfet Drain to Ground. Check Motorola's data for Mosfet spec.

Hope this helps.
