This kit coverts your 2018+ WRX or WRX STI to have LED daytime running lights (DRL) in the fog lamp covers. These are the exact same parts available in Japan, and we import this kit from there.
Note that US cars don't have the exact wiring you need for a plug-and-play installation, and there are some choices to be made in terms of how the lamps are going to operate. We suggest taking a look at this helpful thread on NASIOC, and this post in particular.
For the WRX, it's a little more complicated because the WRX has turn signals down in the bumper, and the new fog lamp covers don't have turn signals. You could switch to STI headlamps (which incorporate turn signals), or modify the C-lights in the WRX headlamps so they act as turn signals.
Kit includes left and right fog lamp covers, LED units, control modules, and JDM plug-and-play harnesses, although the harnesses will NOT plug directly in to USDM or other non-JDM cars.
Fits all 2018+ WRX and STI, with the wiring caveats mentioned above. Note that we will NOT take back this kit if you buy it and then decide the wiring is too complicated. Do you homework first.
