Why would the breaker kick off when adding a run of lights with a switch at the end of the lights?

I really need more detailed information to answer your question. How many lights were added and what wattage bulbs are being used? For a 15-amp breaker, the maximum wattage it would handle would be around 1650 watts. This would be about 16 100-watt bulbs. Does your breaker trip immediately when you turn the light switch on? If you have an ohmmeter you can check the tripped breaker. Put one lead on the black "hot" wire coming from the breaker. Remember, the breaker must be off. Then put the other lead on the ground bar. If the ohm reading is very low, close to 2 ohms, then you have a direct short to ground somewhere in your wiring.

I would guess the headlight dimmer switch on the floor board is bad or has a loose wire. Possibly the head light switch is bad. The headlight switch has a separate circuit breaker for just the head lights.

The headlight switch may be bad. Try replacing. Its the Headlight switch. The switch has a built in Circuit Breaker that self resets. It has become bad and will eventually give it up.

The headlights run on a different fuse from all other lights. Locate and check this fuse. Also the headlight switch may have a circuit breaker inside and after time it will get weak and not reset. Check for power to the switch and if you have power to the switch and then the switch has gone bad and should be replaced.

No. A circuit breaker is a switch, but a switch is not necessarily a circuit breaker. A "circuit breaker" is a device that will open the circuit when more current than it is designed for flows through the circuit. This is an automatic function, and does not require manual manipulation (such as a person physically moving an on/off switch). Resetting is often a manual function. <<>> If taken in the context of a switch opening a circuit or making a break in the circuit then the question, Is a switch a circuit breaker, then the answer would be, yes, as the switch does break the circuit.
