I would also like to present an idea for taillights. Spoiler 1. Number 1 looks a bit "Nissan Fairlady Z"-ish but I think it could fit the vehicle nicely. 2. Number 2's inspiration was from the Nissan Skyline r32, and the head lights of a 2004 VW Golf. As you can see, the brake lights are from the r32 and the turn signal + reverse light are from the Golf 3. Number 3 came from my sheer stupidity my wonderful mind. I'm sure this one looks like another real life car but I can't think of which one. I do think this choice would also suit the 200BX quite nicely. Of course, the orange part (AKA turn signals) can be red instead of orange, and then any white parts are the reverse lights (Duh).
I quite like number 2, reminds me of a Nissan 180sx --- Post updated --- Sorry, just being honest. You did a good job with everything else though.
Oh you're right, it does! The 180sx never even crossed my mind to be honest. Funny how they look almost the same.
