I have a 2016 300S and i think the stock halogen projector headlamps are horrible. Maybe they just need replaced, but anyway im looking to replace with LED, the newer GTR Ultra 2. Before I spend $250 I kinda would like any input from other 300s drivers? Has anyone swapped their headlamps out? What do you recommend?

 

so long you dont have HID setup the leds will plug right in. But you also might need to have a wire harness with a resistor built into it the leds need 12v. most new setups have a variable voltage supply and there for the leds will flicker or not work at all.
