I did the DD tail as turn mod. Instead of using the factory reverse lights, I left them unplugged. I also did not want 4 reverse lights. In the factory reverse light locations, I added 2 red bulbs switched independently to act as rear fog lights. Similar to what is found in Asia/Europe etc.
Rear fog light - EDM/JDM spec, factory look
Or you can add another reverse light in the hitch receiver.
