Why is my 3 way switch flickering?
A poor connection between the light or fixture switch and the bulb can cause flickering. Try gently wiggling the switch to see if this causes a flicker. If it does, you’ve found the problem. If your light is already flickering, try toggling the switch on and off and see if this fixes the problem.
What causes the lights to flicker in a car?
One of the most common causes of headlight flickering is a dying battery. Your headlights rely on power from the battery to function properly.

When lights flicker What does it mean?
Flickering or blinking lights are usually caused by one of the following: Problem with the bulb (not in tight enough, lightbulbs are incompatible with your dimmers) Loose light plug. Faulty switch or dimmer. Appliances or HVAC units pulling large amounts of current on startup, causing a voltage drop.
Why is my light flickering when the switch is off?
“Many times this is due to the circuit inside the CFL charging up, even when the bulb is off. This happens many times when the CFL bulb is being controlled by an illuminated wall switch, because the wall switch uses the CFL bulb itself as neutral. When the wall switch is on, the CFL bulb gets full line voltage.
How does a 3 way light switch work?
Most 3-way lighted switches work by adding a light between their line and load terminals: This actually causes a small current to flow through the load (light) — with incandescent or fluorescent bulbs, it’s not enough to actually cause the light to go on.

Get an illuminated 3-way switch that doesn’t draw current over the load lines. A good sign is if it requires a neutral wire. Of course that also means you’d need a neutral in your switch box to be able to use it. For a newer solution, many dimmable LED should work. The little current that is flowing will not light the dimmable LED bulb.
What causes a 3 way light to go on?
This actually causes a small current to flow through the load (light) — with incandescent or fluorescent bulbs, it’s not enough to actually cause the light to go on. But with your LED blub, it’s enough to at least start the bulb. Get an illuminated 3-way switch that doesn’t draw current over the load lines.
