Without a polarity reversal, I don't see how the bi-directional markers change colors...

Clearly, I don't really understand what you're trying to accomplish here.  Without a complete diagram of how you're wiring this, it's hard to see what it accomplishes.

Yeah sorry I am not super good with those. I checked the voltage on the interior lights and they do change polarity (go from 7 Volts to -7 Volts when I change direction). So my idea for the marker lights will work if I connect them to the wires that the interior lights originally connected to (which is the smoke unit part of the board). And because I found out that it actually has 7 volts to the interior lights, I won't need as large of a resistance for the class light circuit and will only need a 0.25 watt resistor.

I will later change this thread to have a different title name and have pictures updating the status of the project.
