Review on CEC Industries Heavy Duty 12V 2-Pin EF32 Electronic Flasher Relay for LED and Incandescent Bulbs (1-Pack) by Bryan Maignan

Replaced an LED on my 1997 F250. With conventional relays, the turn signals didn't work at all for me. The indicator light on the dashboard barely came on. You couldn't tell it was lit unless it was dark. It didn't blink, it just burned. The LED bulbs did nothing at all. Flashing lights worked but only flashed once every few seconds. I ordered two of these and installed one for the turn signals and the other for the hazard warning lights. The danger one barely fit behind my fuse panel, but I managed to squeeze it in there. Turn signals and hazard warning lights now work great! They blink a little faster than once per second, which is the ideal speed. I couldn't be happier with this product. There is a loud click from the relay which I prefer as my truck is noisy. I don't think it would be too loud for a quieter car, but they are far from quiet.
