Review on 💡 Enhanced Functionality EFL1 Relay by Standard Motor Products - Optimize Your Search! by Jason Rodman

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 as the car has a fairly loud exhaust (built on a 289 with a 2.5" exhaust).
