I've just added the Caterham LEDs, and as the title suggest, turning on an indicator causes that side's lights to blink and also the opposite side's. the correct side seems to be brighter on the front, so switching left and right you get a brighter ring on my leds. I have an LED blinker relay. someone suggested adding diodes????? I don't really know what that means. I reconnected the old lights and everything worked again. if I remove one set of lights, it seems to have the same effect with all lights blinking. any ideas? J
