Okay, well that was a mouth full. This particular OLM turn signal harness is meant to be used with OLM Facelift bezels that have a turn signal feature.

*Who does this product benefit? If you have a 2018+ WRX Limited with LED headlights or 2018+ STI (all of them have LED headlights), you can connect this to the OLM wiring, block off the other adaptor (to prevent it from grounding ever grounding out) and tap the turn signal wires that go to your headlights. This will let you divert the turn signal features to your bezels.

If you want to just use your new bezel turn signals, remove the bulb from the headlight housing. Otherwise you can use both. Just remember that a standard turn signal bulb will not blink as fast as an LED turn signal. You can upgrade them to LED though! Just see our related items at the bottom of this listing.
