Fuses and circuit breakers are to prevent fires only. They are not
designed to prevent failures. That is why it costs $280 to get your TV
fixed and the fuse inside  is still good.

The proper size fuse is selected to match the current carrying
capability of the wire that recieves power from the fuse/breaker.

I've never looked for them but I think all my american vehicles have them built 
into the headlamp circuit.
