Flasher for LEDs

[Mert]

I have owned a 1960 BN7 for over 24 years. Recently I switched out the incandescent bulbs with LEDs purchased from "Classic Auto Leds". The recommended flasher was a Tridon EL-13. My Healey has a Positive Ground. The flasher will not operate the LEDs. I have tried an F3 Super Brite flasher - works, but panel light constantly blinks. I am in need of assistance. Any assistance would be appreciated.

I don't think you can use LED's with positive ground -- unless you isolate your lamps to make them negative ground locally. The "D" in LED stands for diode, which means they only pass current in one direction. I have an LED light brake light on my Healey and I had to convert my system to negative ground. It's not too hard unless you have a radio or other positive ground accessories such as an alternator.

You can get LEDs that are positive ground. They will be marketed as such. If there is no mention of polarity, most likely they are negative ground.
