When I replaced my headlights recently I was surprised to find that several of the wires inside the harness were cracked and had exposed copper. These were inside the headlight housing so not exposed to the elements. And the bulbs I replaced looked ancient, so I may be the first person to have opened them since they left Stuttgart 21 years ago.

I wonder if it's the heat from the bulbs? I doubt it though since there aren't any cracks in the engine bay wiring. I don't think I've ever seen wiring insulation that isn't super high voltage and constantly exposed to the elements (like electric fence runners) crack their insulation like that.
