It's funny how all of these usually cheap personalizing fads come and go. I recall...the whole ricer movement, small tires that stuck way out from body (broke wheel bearings and hubs; ended that fad fast), horizontal pinstripes on tail lights, front fender mounted turn signals (for that JDM, Euro look), spinners...on and on. Now it's fender mounted fake louvers and the dumbest and most dangerous things to hit the street in a long time...DONKS.
Fender mounted turn signals are actually a good idea.
