TYC clear headlights and TYC clear turn signals with orange bulbs in both the DRL and the turnsignals.
I don't know if they make that version anymore, it was certainly the best halogen headlight out there for the NBS which was only short of the Xenarcs.
A lot of people run funky headlights on the NBS trucks and I think it looks like piss. Personally I like the clear yet still appears to be OEM look but you know its been changed it that makes any sense. I only ran the clear turn signals for probably a year and went back with new clean oem turns and I think it looked better. I would just buy a new set of turn signals find a nice clear set of headlights (clear not black and not the starburst pattern crap) and these tails:

I could go on and on and on about suggestions....
Like remove the door molding.... get color matched door handles..... etc etc.
Not to spam you anymore than I already have but this is one of the best setups on a white NBS, minus the crap starburst turn signals i previously mentioned
