Mala did you wake up too early, or thought you'd sign in one last time after a night of drinking? So much hostility towards electricity.
The issue I've heard of is from people that don't install their work carefully and end up placing a wire where it can be chafed later, or install a short immediately. The short has the possibility of doing more damage. As the wires begin to melt, it can cause other wires to short if the fuse doesn't go fast enough. I've read rumors of people frying their ECU or their voltage regulator due to the short.
So, does the light cause any problems? No. They work just fine. Sloppy craftsmanship has killed many a project. Just try to keep the smoke in the wires. They put it in there for a reason. An internet search will explain that the factory that makes the wire installs smoke between the wire and the insulation, it gives the electrons something to jump from particle to particle until it reaches it's final destination. The wire is in there to give a place to bolt it down, it serves no other function besides a mechanical joint. The insulation was not strong enough to serve as the anchor, but does a great job of holding the smoke together. You may want to try to argue this with me later but I will win. Just ask anyone that has accidentally let the smoke out of their wiring if the lights still worked. Let enough smoke out, no lights.
