I got it figured out. You go to the page where you make changes to the engine sounds, lights, etc. Then click on either the front or rear light and under the upper box there is a box that shows the wire color for that light. If it shows a white wire, click on the wire picture until the yellow wire shows up. Then go to the other light and do the same thing, change it from yellow to white. Then save it. Also be sure to change the motor rotation to reverse.
