Which wires go on a 3-way switch?
With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire. When the circuit’s power is turned on, any of these may be “hot,” depending upon how the switches are toggled.
Which wire is the common wire on a 3-way switch?
Black wire

How do you hook up a headlight switch?
Hook up the existing headlight wires in the proper order, consulting your wiring diagram for which wire goes where. You can also do this, through trial and error, by connecting the wires until the headlights and driving lights come on when the toggle switch is turned on.
How does a 3 wire light switch work?
The simple explanation is that a 2-wire system does not include a Neutral wire at the light switch, the 3-wire system does include the Neutral at the switch. This is the most common lighting system in Europe, almost all homes use this system, especially in the UK and Nordic regions.
Can a toggle switch be used as a headlight switch?

Is there such a thing as a 2 way light switch?
But there is a special switch called ‘Two Way Switch’, which is the an important component in the implementation of Staircase Lighting. So, before proceeding to learn about the wiring of a 2 way switch, we will learn about the Two-Way Light Switch, which is the main element of the 2 Way Switching, irrespective of the type of wiring used.

What’s the difference between 2 wire and 3 wire lighting?
If you have a 2-gang or 3-gang switch you may have black and grey wires, however these will have a brown sleeve on them as they are also switched live wires. The 3-wire system is less common than the 2-wire system, it includes a Neutral at the switch as well as the Live and Switched Live wires. Figure 2: One example of a 3-wire lighting System.
