OLM Switchback LED C-light DRLs for Headlights by Profile Performance

2015+ WRX / 2015+ STI

Ships for free in the 48 states
A great solution to the dim, factory Subaru C-light. Added functionality with built in turn signal feature. Retrofit your headlights with parts from OLM. Sold as a PAIR. Only fits 2018+ WRX Limited / STI models. NOTE: We strongly recommend testing the lights before installing them inside the headlight housing.


The German Style DRL You've Been Looking For

Let's take your headlights to the next level by introducing some ultra bright LED boards in them. Also add a sweet switchback turn signal function as well. This is the way they should have been from the factory.

Other items you can modify while you have your headlight open are the sidemarker covers, and you can also paint the chrome housing another color like flat or gloss black.

The end result can be a truly spectacular, custom set of headlights that function as well as they look.

NOTE: T10 connectors were originally designed for the original vehicle application. These can be cut off. Black wire is a ground wire and white is positive. We recommend extending these wires and connecting them to an accessory powerpoint (see additional tab).

SubiSpeed Install Video

This video was made for the original vehicle application, however the process is similar.


If you do not have spare butyl sealant in hand, RetroRubber or other butyl sealant is REQUIRED. The OEM sealant cannot be reused! TRS RetroRubber can be stretched to the proper length and width to fit the headlight casing channel.

Optional - SubiSpeed Sidemarkers

These sidemarkers are a direct fit replacement for the factory orange sidemarkers that come with 2015+ WRX and STIs. This is a great modification to perform when you're working on your headlights.
