Diode Dynamics carries a myriad of LED lighting products for vehicles. The kit I got replaces the stock C-Light with a much brighter sharper light. It's quite a bit of effort to install, as the light rests inside the headlight housing. To reach it, the entire front bumper cover must be removed as well as each headlight housing. While these lights were being installed, the orange corner reflectors were blacked out and the light was re-wired to activate the JDM Fog Light Bezel LED light, as the two lights turn on together. The effect is a much sharper and more aggressive looking headlight assembly that doesn't look like an aftermarket modification. These brighter C-Lights are easily visible during the daytime and are even more obviously bright at night. It's a clean finish that really sets off the front-end.
I would recommend this to anyone with a 2015-2017 WRX or WRX STI looking to improve the look of their car while still giving it a clean stock appearance. I would especially recommend this for anyone with a Base or Premium WRX, as the lights really transform the aggressive look of the headlight. Plus, having the light apart gives you the chance to make other aesthetic changes. It would have been a little tricky to do this install on my own not having any experience doing something like this, but I was lucky to know someone who had done this before with their car and had a helping hand.
