Getting white dots on the edges of renders caused by lights.

I’m rendering a model of the enterprise (Star Trek) I modelled from scratch. It’s taken ages to create. When I rendered it out with all of the lights turned on, white dots appeared on the edges of the model. Sometimes on the model itself. I eliminated most of it be removing lights. But I’m at the point where I can’t remove any more lights, because it would wreck the model. So, how do I fix my issue! Really starting to ‘P’ me off!
