What I do is add omni lights to the engine. Line them up where you want too. Then go into the Environment/Effects editor and choose Lens Effect. In the effect you will find an option called Glow. Add the glow element then choose each Omni Light one at a time. This will make the Omni light look like glowing orbs when viewing the camera view. Mess with the colors, intensity, and size to get what you want, then link the lights to the object. It may not be the best way, but I think it looks okay. Hope this helps.
