The circuit for blinking an LED using transistors is called an Astable Multivibrator. To understand this circuit you need to know how voltages and currents behave around resistors, capacitors and diodes (which is something you can learn in Ohmify). Here's an overview of what happens:
The dimmer has so little current to work with that whatever voltage it does reduce ends up manifesting in the LED bulb as choppy, resulting in flickering, or strobing, or another dimming error. The key is to supply sufficient load or current to the switch.
Sep 13, 2016 · Just the normal ones, i dont have the swish LED lighting package so just 3x bulbs! Anyway, this is the weird part. All fine and working well. Get in and lights fade on, put key in ignition, lights fade out. Perfect. Get out of car, lights fade on again. Lock the car, light fade out.... BUT dont fully go off!! they flicker very very faintly.

Check for an Electrical Short. Most power supplies have built in electrical short protection, this will cause the power supply to turn on and off, almost like a blinking effect. Smoke or burnt wires are also a common sign of an electrical short.

Feb 11, 2019 · Hopefully those looking for practical information on electrical circuits and wiring LED components found this guide first. It’s likely though, you’ve already read the Wikipedia page about Series and parallel circuits here, maybe a few other Google search results on the subject and are still unclear or wanting more specific information as it pertains to LEDs.
The LED blinker circuit is built around a 555 timer IC that is wired as an astable multivibrator here. The circuit is using 12 LEDs, which will blink in flip flop manner, the blinking speed can be controlled by the 100K variable resistor. The circuit is directly connected to the AC mains therefore do not touch it when it is connected to the AC.
