I bet that annoys insurers a little. After a collision, the scene forensic agents will often check to see if the brake lights are burned out. If they aren't, it suggests the brakes weren't applied before impact, giving them a potential clue about the state of the driver at the time of impact. (note: it takes several bits of forensic evidence to cement the deal - this is just one artifact of many that when compiled, inform the insurers of what likely went down.) Nowadays LEDs are a lot more common, so that one clue disappeared with their introduction.
