Create points for the lights in SOPs whichever way is most convenient. It kinda depends on your situation. To now move the lights to the point positions, you'll need to use CHOPs. In a CHOPnet, use the Geometry CHOP to import those light positions in Animated Mode. You'll need to name the imported channels to some naming convention that matches your OBJ lights. Now just export this to your light Translate parameters. If you need rotations, then you can add some channels for them in CHOPs as well.
