It's extremely easy to make the lights glow in DAZ under IRay. You just add an emissive shader to them. 3Delight it can be done, but it's not as easy. Are you using it in Iray or 3Delight. If it's Iray? I'll be happy to walk you though how to do it. SImon-3D, I've got that set, I'll work up some Iray materials for it . Give me a week.
