I'm trying to find a flasher that will work with LED bulbs on my '67, which has a (repro) stock wiring harness from Walcks' that was recently installed. I bought these LED bulbs from Super Bright LEDs (two red and two amber): 1157 LED Bulb - Dual Function 27 SMD LED Tower - BAY15D Retrofit | LED Brake Light, Turn Light and Tail Light Bulbs | LED Car Light Bulbs | Super Bright LEDs They work great in brake and parking light modes, so I know the polarity is correct, but they will not work in turn signal mode. The currently installed Novita flasher is electronic, and works fine with incandescent bulbs. It's supposed to work with LEDs bulbs as well, but in this case it doesn't. Has anyone found a flasher that works well with LEDs?
