Review on Alla Lighting Decoders Flicker Resistor by Ryan Morrow

Be sure to watch the installation video to see how to install correctly. I installed myself first, not workie. There are no positive or negative marks, and the setup is literally reviewed and tweaked. I installed LED turn signals in my car and they flashed quickly. I installed the first one and it actually stopped blinking fast on both sides so I only used one. It's been 1 month now and it's still working perfectly. The resistor block gets very hot, so be sure to screw it to the metal like the instructions say. Grounds it, but also allows excess heat to dissipate through the car's metal.
