Vehicle headlights are protected with circuit breakers instead of fuses because, when light bulbs fail, there is an ionizing arc internally that causes high current. You see that at home - when a light bulb fails you see an instant of very bright light.This pulse of high current can blow a fuse. It also can trip a circuit breaker, but the circuit breaker is designed to reclose while, once a fuse is blown, it stays blown. Headlights are a critical safety device. It is better to attempt automatic reclosure following a fault, than it is to leave the headlights off, in case the fault was temporary.
handling the circuit breaker
There isn't, the contacts in a circuit breaker are plated with silver.
Before you change a circuit breaker it has to be established that the breaker is at fault and not some other part of the circuit.
If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.

In the breaker box
The circuit breaker for the headlights is built into the headlight switch.
The circuit breaker for the headlights is intergrated with the headlight switch.
Back then the headlight circuit was protected by a circuit breaker that was built into the headlight switch.
There is no fuse for the headlights in that truck. The circuit is protected by a circuit breaker located inside the headlight switch.
No headlight relay listed. The headlight circuit breaker is integral with the headlight switch.
The headlights are not fused. The headlight switch has a built in circuit breaker.
The headlights do not have a fuse. There is a circuit breaker built into the headlight switch.
It is usually located in the headlight switch. It is a automatic reset circuit breaker. When a short occurs it rapidly blinks the headlight circuit on and off so the headlights are not completely lost to allow you to pull off the road safely at night.
