Blackout rear lights? Not feeling it. I'm not sure if it's legal, or even close to being legal. The last thing you wanna do is to piss off JPJ/Polis on a roadblack. Sometimes they get ticked off for the slightest mod, and trust me you don't wanna be the victim of a roadblock. It might be cool if you're not caught. But when you, pick up saman, pay for it, re-check again with JPJ, yada-yada-yada. Not worth it, bro.
I agree with Solo - black car, black rims with blackout rear lights may be a nice touch. May be.
