Used: 1972 Dart Reversing Relay for rear brake LED lights and turn signals. One relay was under the steering wheel, the other behind the ashtray/radio. Works amazing, fixes fast blinking or no blinking when using LEDs on older cars.

Ideal for classic cars. The two-pin block works great with regular light bulbs. I haven't tried it with LEDs yet. I suspect you need a pull-up resistor to make them blink. But they are durable, don't waste your time with cheaper brands.

If you type in "LED Flasher" and it shows the results, you should assume that it works with LED lights. If you allow the user to incorrectly answer IE's "Customer Question" "Electronic Blinker eliminates excessive blinking when using LEDs", then who is to be held responsible for false advertising? The turn signal will NOT work with LEDs, I should have known better, I'm sure the turn signal would work fine with standard bulbs.

When I installed LED lighting in my 1970 Mustang, the mechanical turn signals had trouble and often behaved as if the bulbs had burned out - they burned constantly, not blinking. I replaced them with these two controllers (one for the hazard lights and one for the turn signals) and they work like a charm and give a nice, strong, steady, even flash! I also have a good sentimental feeling when they are in my car as my father was a parts designer for Standard Motor Products in the 1970's and…

Used on a '65 Mustang with front and rear LED turn signals. This blinker needed load resistors to work with the LEDs (without them it won't blink and the light won't work). After I installed the terminators, everything worked beautifully; flash rate is fairly high, about twice a second, with a good, regular rhythm; As soon as you turn on the turn signal, it will flash immediately and go off immediately when the turn signal is deactivated. makes a nice, fairly loud clicking noise which I prefer…
