I believe its just white on the pro and white/amber on the trailhunter from factory. Im sure you could buy the parts from Toyota and swap them out. I doubt you can order the changing amber/white from factory on the trd though. Its not an option on the tacoma build on the website.
The fact that they both have the same HP and TQ makes me worried the TRD Pro and Trailhunter with the hybrid powertrains will also be premium fuel only. Hoping that is not the case.
