Just wanted to throw a review up here about ERM. Tony(the owner) has been great to work with and has helped me over the phone when I ran into an issue. I recently installed his ISO headlight flasher on my 2017 Dodge Charger civilian version. I installed it so it flashes the LED DRLs instead of the highbeams. Pretty straight forward and works perfectly. My DRLs still function normally but once I trigger my warning lights, it overrides the DRLs and makes them begin flashing back and forth. He also makes plug and play harnesses so you don't have to cut any of your factory wiring which was convenient.
