Thanks, I tried that but it didn't have any effect,
however I've been able to determine now that it only happens when the headlight switch is turned ON. In other words, with the headlight switch OFF, the LED"s work properly. They light up brightly when I push the brake peddle, and they flash properly when I engage the turn signal lever.
Something else is happening when I turn on the headlights that is interfering with the LED.
Maybe the 6 ohm/50 watt resistor is too much?
