There's a self-test function...I think you start with the lights turned on and the ignition off, then start the ignition. The car has to be facing a wall or it should be dark out, so you can see the headlight beams. They should dip momentarily when you start the ignition, then come back up. Even if they do work, they still depend on a little arm connected to the front suspension to be connected, so check that too if you're not sure.
