Positive – The wire for the positive current is red. Negative – The wire for the negative current is black. Ground – The ground wire (if present) will be white or grey.
Q. What color is the reverse light wire?
Reverse lights on a vehicle must be white in color, and these come standard on all vehicles. the easy thing to do is just look at the tail light from the insde as if you wanted to replace the reverse light. the 2 wires are going to be the positive and negative. most likely the negative wire will be a black wire.

Q. What color are turn signal wires?
Trailer Wiring Has 5-Wires White, Yellow, Green, Yellow/Brown, and Green/Brown On a 4-Way flat trailer wiring harness, white is the ground, brown is running lights, yellow is left turn signal and green is right turn signal.
Q. What do the colors on wires mean?
US AC power circuit wiring color codes The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
Q. What are the white black and red wires?
According to standards in use since the mid-1900s, a wire color code identifies the purpose of each wire in an electrical circuit. The white wire is always neutral, and when the cable has only two conductors, as most 120-volt cables do, the hot wire is black. The red wire is for the light switch.
Q. Can you connect black and red wires?
It’s possible to link two red wires together or a red wire to a black wire.
Q. Are red and black wires interchangeable?
Red and black wires are current-bearing, and their positions are interchangeable.
Q. What wires are black and red?
Black, red, white with black or red tape will always indicate a hot wire. The term “hot” means these wires carry a live current from your electric panel to the destination.
Q. Can I leave the red wire unconnected?
Look for the other end of the red wire in the box that has the fan switch. It could be unconnected in the box. Someone may have planned ahead and provided a second wire for a switched light on the fan. Just leave it.
Q. What happens if you switch red and black wires?
If the black and red are a hot and switchleg, then if connected to the black from the fixture it would mean the light is always on. If the black and red are 220V between them, then connecting them to the black from the fixture would burn up the fixture. You need to know which wire is 120V to neutral.
Q. Why do I have 2 black wires?
Black means hot, white signifies neutral, and green indicates ground. However, if you need to rewire a light switch or a plug socket, you may occasionally come across two black wires. It’s essential that you determine which black wire is hot before proceeding.
Q. Why do I have two black wires and one red?
The black wire is the “hot” (or power-source) wire. It would be connected to the power-source wire coming into the junction box, and if there was any pass-thru (to other switches & outlets), it’d be connected to those. The red wire would the “load” wire (controlled by the switch.)
Q. Why does my light switch have 2 white wires?
Could be 2 whites if the person wiring it did not follow convention and use a white to go to the switch so black could come back. As posted elsewhere if it’s 2 whites then you need to determine which is hot and which is neutral, then put a piece of black tape on the hot one for future reference.
