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

I had no idea that LED lamps cause so many problems. I have a 1971 F-250. I installed new LED lights and had trouble with the turn signals. I have 4 volts on the wires. No blinking and just a barely noticeable bulb on the dash turn signal. I tore everything apart to find a short or bad ground in my wires. Nothing. I was confused. A friend mentioned that the bulbs could be the problem so I put my 40 year old bulbs back in and everything worked perfectly. I thought I wasted all my time and money. Luckily another friend mentioned that this was all I needed. and of course enough. After replacing the "clicker" everything worked. What a pain in the ass. I hope this saves you the time I wasted. And FYI, some front LED bulbs don't work like parking lights and turn signals on older cars. I could get sidelights and front turn signals, but not both. When the light was on, I had no turn signals. It's a lightbulb problem. Read reviews before buying.
