Review on CEC Industries EF32RL Flasher by Chris Fisher

Worked well to convert my truck (1986 F-250) to LED headlights. I used two of these to replace the factory turn signal and hazard relays. I hooked up the emergency gear relay with no modifications, but I had to change the polarity of the turn signals (pulling the wires out of the fuse box and swapping them) to make it work. I can still hear it clicking for a second or two after turning off the turn signal. It doesn't look like the lights are constantly flashing, but you can definitely hear the relay working. I don't know if this is a "feature" of this relay or if I still have some wiring issues I need to track down.
