These types of replacements can become more tricky the more wires, the more challenging. For example, you might see this if you have a light fixture with a three-way switch or a ceiling fan. These all typically mean there are other switches. In some cases, you might notice yellow or blue wires in the junction box or other colors. If you see a red wire in the ceiling, it usually represents a switch that will control the light fixture. The same goes for the black and white wire in the ceiling. The white wire is the ground wire and is neutral, while the black wire is live. In a simple fixture with one light switch, you would perhaps have a black and white wire in the fixture. Usually, the different colors of the wires represent specific things. This makes replacing an existing fixture with a new one reasonably easy–until you realize your fixture has two black wires. Normally, light fixtures feature different color wires that match the wires in the electrical box in the ceiling. But, if you aren’t comfortable dealing with electricity, then your best bet is to call an electrician. It’s best to test the fixture first before doing a complete replacement, so you don’t have to potentially uninstall the fixture. If you need to wire a light fixture with two black wires, your first step is determining which wire is which. Luckily, there are other clues you can look for, like the wire texture, or you can use a voltage tester. But, if you need to wire a light fixture with two black wires, it’s essential to determine which one is hot and which is neutral. Typically, light fixtures feature a black wire and a white wire which you connect to matching wires coming from the ceiling. But unfortunately, sometimes, wiring a light fixture isn’t always as straightforward as you would hope. Changing out a light fixture is usually relatively simple, thanks to color-coded wires. If you’re renovating or perhaps dealing with a flickering light fixture, you can attempt to do a DIY replacement.
