These turn signal lamp units can be used to replace the stock STI turn signals in the door mirrors, or to ADD them to WRX cars that didn't come with them in the first place. The lamps feature a smoked lens for added style, a SEQUENTIAL turn signal function, and a white running lamp.

For WRX STI cars, these are a plug-and-play replacement (with the exception of the white running lamp -- see below). Just remove the stock lamp, and plug in the new lamp.

For non-STI WRX cars that don't have the mirror lamp from the factory, we include extra parts so you can add these to your car. You get left and right OEM mirror caps with provision for the turn signals, plus wiring harness adapters to plug the turn signals into your factory wiring. (You'll insert pins from the harnesses into the factory plug.) Note that the mirror caps are UNpainted. You will want to paint, wrap, or otherwise finish the caps to your taste. We wrapped ours with gloss black vinyl, which was easy and inexpensive.

For all the cars, you'll need to custom-wire the white running lamp function using the included wire taps. Tapping into the door wiring harness wire as shown will have the white running lamp on any time the key is on.

Set of two lamps. Fits all 2015-2021 Subaru WRX and STI.
