I just recently tried to install my switchbacks, and only the amber lights up for running light (glitches right out) and signal works fine (but the trucks blinker hyperflashes with bulb out). Anyway I tried decoders which are a waste of money. The bulb has white running lights, but once the amber gets power it completely takes over which can be hazards or signal, then return to the white once the amber has no power. I used a multi-meter to check the connections, I found that my running lights get 12V consistently and the signal gets 6V consistently with only the parking lights activated, once I signal the 6V fluctuates. I know I need resistors but what about changing the flasher relay or something? For these bulbs to work I need to eliminate the 6V power in parking mode. If anyone has any other solutions or can share their set up for their switchbacks it would be much appreciated. Have a 2013 ram 1500 bighorn.
