I'm thinking about hanging some rope lights in my bedroom for ambient lighting on the walls close to the ceiling. Do these kinds of lights have heat issues or would they be a fire hazard?

If they are not covered, there should be no problem with them. Of course, when you get some sloppy quality product, it may become dangerous, but that is the same with just anything...

Yeah.Thanks for the idea.

If its LED i dont see much issu

If its incandescent beware - they have the feature of breakdown shunt in each lamp in order to keep the series circuit going in case a lamp or few burn. After few lamps it getsoverpowered and will heat more and more, the last lamps will burn spectacularly and can explode, emitting incandescent hot particles (the filament will probably be vaporized, but lead wires and maybe even glass pieces probably won't). Incandescent pieces fall into bed = risk of fire

I use a 24v LED strip powered by a 19v laptop power supply
