They are aftermarket lights that come tinted but they are horrible quality. The splitter is from sentranation.com. Check out my IG for more pictures of the headlights that I have tinted now Clark_Kyle97
I would say wheels/tires and suspension first. And actually do a little additional research before you buy anything. I made the mistake of rushing into my build and it caused me to keep having to repeat steps later down the road cause I didn’t do it right the first time around!
