As you examine the switch, you'll notice there are typically three different types of wires connected to it:

  • Black wires - These will be attached to the black or brass-colored screws on the switch. They are considered “hot” wires and carry electricity from the power source to the destination, such as a switch or an outlet.
  • Copper or green ground wires - These are connected to the green or copper-colored screws. Copper or green wires are used as ground wires in electrical circuits. They provide a path for electricity to safely return to the ground in case of a short circuit or fault, helping to prevent electric shock and fire hazards.
  • Neutral white wires - These may also be present. They are a part of the electrical circuit and are responsible for completing the circuit back to the power source.

Identifying a hot wire on a lamp can be tricky, however, you can make it easy by reading this article “6 Simple Ways to Identify Which Lamp Wire Is Hot or Neutral With & Without Multimeter”. Take your time and unscrew each of these wires from the switch terminals. If the wires are attached using push-in style connectors instead of screws, you can use a small screwdriver to gently release them.

After successfully disconnecting all the wires, you are then able to fully detach and remove the old switch component from the lamp. With the old switch successfully disconnected, you're now ready to install the new replacement switch. Just be sure to connect the wires back to the proper terminals, following the same configuration as the old switch.

Many homeowners face this frustrating issue. You can find out more details about flickering light in the article “Why Is My Lamp Flickering? 10+ Causes, Solutions and Safety Tips

Lights Too Dim Or Too Bright


  • Incorrect bulb wattage: This is absolutely the most common culprit. Using bulbs with a wattage higher than recommended for the lamp will produce harsh, bright light. Conversely, bulbs with a lower wattage will result in dim illumination. 
  • Dimmer switch issues: Faulty or incompatible dimmer switches can definitely cause problems. A malfunctioning switch might not dim the light properly, leaving it overly bright. Additionally, some dimmer switches aren't compatible with certain LED bulbs, causing flickering or inconsistent dimming.
  • Inadequate lighting design: This applies more to entire rooms or areas in a house, rather than individual lamps. Poor lighting design happens when the number or placement of light fixtures isn't sufficient to illuminate the space properly. This can lead to specific areas being overly bright or uncomfortably dim.


  • Check the bulb wattage: Selecting light bulbs with wattage that is either too high or too low for your fixtures can lead to lighting that is excessively bright or overly dim.
  • Replace dimmer switch: Malfunctioning or incompatible dimmer switches can cause flickering or poor dimming control.

Lamp Shade Won't Stay in Place or Wobbling

  • Loose harp: The harp is the metal structure that serves to hold the lampshade firmly in place. It typically screws onto the lamp base and has a finial (top screw) that secures the shade on top. If the harp itself is loose on the base, the shade will wobble.
  • Shade fitter incompatibility: The shade fitter (the ring at the top of the shade) might not be the right size for the harp. This can cause the shade to sit crooked or not grip the harp securely.
  • Broken harp or finial: If the harp or finial is damaged or bent, it won't hold the shade securely, leading to wobbling.


  • Adjust the fitter: Ensure the lamp shade fitter (the part that attaches the shade to the lamp) is properly secured and tightened.
  • Replace the harp: If the harp (the metal frame that supports the shade) is bent or damaged, replace it with a new one.
  • Use a shade retainer ring: Consider adding a shade retainer ring to help keep the shade in place.
  • Fix the base: The problem could stem from the lamp base being wobbly. Inspect the lampshade to ensure it is properly aligned, and make any necessary adjustments. See our guide on how to fix a wobbly lamp base here.

Buzzing or Humming Noise


  • Issues with dimmer switches: Certain dimmer switches may produce a buzzing sound when used with specific bulb types, such as LEDs. Make sure your light bulbs can work with your dimmer switch. If your LED dimmer is older, it might not be fully compatible with modern dimmable LED bulbs.
  • Loose electrical connections: Ensure the power is turned off and inspect the fixture for any loose wiring. With the power supply to the fixture disconnected at the junction box, secure any loose connections.


  • Tighten the lamp base: A loose lamp base can cause the lamp to vibrate and produce a buzzing or humming sound.
  • Check the socket: A worn or damaged socket can also lead to these types of noises.
  • Inspect the wiring: Check for any wires that are disconnected, damaged, or exposed.

Remember, if you're unsure about the problem “Why is my lamp buzzing?” or if the repair seems beyond your skill level, it's always best to seek the help of a professional electrician.

Even with the best intentions and a step-by-step guide, you may encounter some challenges during the lamp repair process. Here are some tips to help you overcome common issues:

  • Make it a habit to check your light bulbs and tighten them as needed.
