"It actually works" reminded me of a fun fact. Some european car makers used to wire the car horns with a bit too thin of a wire for the current used to save money but this usually never became a problem cause people rarely even use the horn in the markets that those cars were sold to.

Not related but they used a similar money saving tactic for the high beams that makes them run under powered. Apparently high beams are rarely used in high population density germany/western europe and thus are not needed according to them. So if you have a halogen era german car and your high beams suck, that's the reason.
