This is one of the reasons I love my 20 year old car.
My wife's 10 year old car's headlight bulb went out. I had to remove the front bumper to get the headlight out to get to the bulb. When I opened the back of the headlight there were bits of colored plastic all over; the insulation on the dozens of wires inside had dried up, cracked, and were flaking off - probably do to the motion of the adaptive lamps, exposing the bare wires. If any of these bare wires shorted out it could easily have started a fire.
Both headlights were like this.

- jdsully 7y agoIts quite possible for even fused circuits to cause fires. If there is a high resistance short then it will heat up without drawing enough current to trip the fuse or breaker. I don't know how common this is in cars, but it is quite common in household wiring. It was especially problematic with aluminum wiring used in the 70s but can happen even in copper circuits.
