What causes LED lights to flicker when dimmed?
What causes LED lights to flicker when dimmed?
The main cause of flickering with dimmable LED light can usually be traced back to the dimmer switch. Dimmer switches come with a minimum compatible load (in short, the amount of Watts it can process). That’s why it’s important that you get a compatible LED dimmer switch to avoid any potential flickering.

How do I stop my LED lights from flickering in my car?
Installing LED DRLs leads to flickering headlights and dashboard errors. This is because LEDs draw very little power compared to halogens and car computer systems are designed to recognize stock halogen bulbs. To fix LEDs flickering, install special CANBus adapters, voltage boosters or resistors.
Does dimming LED lights shorten their life?
Since dimming, either by reducing current or by pulse width modulation, results in lower overall junction temperatures, it will have no negative impact on LED life; it might even extend life.

What happens if you use non dimming LED bulbs on dimmer switches?
If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.
Why is my 12v LED light flashing?
If you have a loose connection for the LED itself, the vibration from driving will cause all sorts of flicker. Then again, a fuse that’s getting old or going bad will cause the LED light to have a flickering problem. Headlamps, brake lamps, and fog lights all can run off the 12v system with super bright capacity.
Why do lights flicker when using dimmer?

Do LED lights work with a dimmer?
Most LED bulbs will not dim with a dimmer because of the technology described above. Cree, however, has manufactured a 9 Watts, solid state LED bulb in an Edison base that can replace any incandescent or halogen bulb in a socket connected to a dimmer switch. This is a revolutionary new product that was designed specifically to be used with dimmers.
Can you put a dimmer on a LED light?
Contrary to popular belief, it is possible to put a dimmer switch on LED lights without the help of a professional. However, you need to familiarize yourself with ways to safely install a dimmer switch to ensure that it adheres to the National Electrical Code requirements.
