You will actually need 2 3-way switches to control something from two locations. The first switch will receive the power, while the other will go directly to the load being controlled. The switch getting power will have the hot lead connected to the common terminal. The other switch will have its common terminal connected to the hot lead going to the load. Two "travellers" will be connected between the other terminals on the switches. They will be connected switch-to-switch. And don't forget that your neutral coming from the power feed will be connected to the load. Also don't forget to connect ground wires.
To hook up an overhead light in the kitchen to a two-way switch, you will need to run a 3-wire cable between the light fixture and the two switches. Connect the black wire of the cable to the light fixture, the white wire to the neutral wires, and the red wire to the two switches. At the switches, connect the red wire to the common terminals and the black and white wires to the traveler terminals.
to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch
No. For any 3 way switch installation you need 2 "travelers" between switches and these conductors cannot be used for any other purpose. The 3rd wire is used for a neutral or switch leg, depending on the needs of the circuit, but is not connected to both switches. The neutral is not connected to either switch.
"Travelers" are the two switched wires running between three-way (or four-way) switches to operate lights from multiple locations. Depending upon circuit configuration (swx/swx/lt or swx/lt/swx), the third wire in a "3-way" cable could be either "hot" or "neutral" at all times and the bare copper wire is always an equipment grounding conductor.
Wire the two 3 way switches using 3 wire cable (red, black, white and bare). Then connect the first light to the others using two wire cable (black, white and bare) kind of like a daisy chain. The power goes to the first 3 way switch, then switch one goes to switch 2 using the 3 wire cable (even though it has 4 wires in there), then the second switch goes to one of the lights. Hope that helps.
To wire 3 light switches in one box, you will need to connect the power source to the switches and then connect the switches to the lights. Use a diagram to show the wiring connections for each switch and the lights.
To wire a 3-way switch with a 3 lights diagram effectively, you will need to connect the switches and lights in a specific way. Start by identifying the power source and connecting it to the first switch. Then, connect the first switch to the second switch using a 3-wire cable. Finally, connect the second switch to the lights using another 3-wire cable. This setup allows you to control the lights from two different switches in the room.
To wire 2 lights with 2 switches in a single circuit, you will need to connect the power source to the first switch, then run a wire from that switch to the first light. From the first light, run another wire to the second light. Finally, connect a wire from the second light to the second switch. This setup allows you to control each light independently with its respective switch.
To hook up an overhead light in the kitchen to a two-way switch, you will need to run a 3-wire cable between the light fixture and the two switches. Connect the black wire of the cable to the light fixture, the white wire to the neutral wires, and the red wire to the two switches.

To wire a 3-way switch with 2 lights to effectively control the lighting in a room, you will need to connect the switches and lights in a specific way. The power source should connect to the common terminal of the first switch, with the travelers connecting the two switches. The first light should be connected to the first switch, and the second light should be connected to the second switch. This setup allows you to control both lights independently with the two switches.
To wire a 3-way switch with multiple lights, you will need to connect the power source to the first switch, then run a 3-wire cable between the switches. Connect the cable to the second switch and then run a 2-wire cable from the second switch to each light fixture. Connect the wires according to the wiring diagram for a 3-way switch setup.

Check for burned out bulbs Check for a broken wire between stop light switch and brake lights Check for corroded light sockets
If it is an extra wire, don't combine it with any. Cap it off by itself. Three conductor wire is intended for 3 way switches, or fan-light combo use. If that was three-way-ed through the light box, you'll have to ask the question differently.
* Burned out bulbs * Defective lamp socket(s) * Broken wire between flasher/switches and actual lamps themselves
