Product Overview
When upgrading to aftermarket headlights on a 2007-2018 Jeep Wrangler JK, one of the most common challenges is maintaining proper turn signal and parking light function alongside the new headlight assembly. The ORACLE 5851-504 Y Splitter Adapter solves this cleanly - no cutting, no splicing, no guesswork.
The adapter connects directly to your vehicle-side factory plug for the front grill Turn Signal / Parking Light circuit and splits it into two separate plug-and-play outputs. This allows you to simultaneously power your upgraded headlight assembly and an additional device - such as a switchback DRL/turn signal module - from a single factory circuit.
This adapter is a required installation component when fitting ORACLE's 5769-series 7" High Powered LED Headlights and Switchback LED Halo Headlights to the JK platform, ensuring both the headlight and the switchback turn signal function correctly without any wiring modification to the vehicle.
Sold individually. Most JK headlight installations require (2) adapters - one per side. Order quantity accordingly.
Vehicle-specific fitment - designed for 2007-2018 Jeep Wrangler JK front grill circuit
Y-splitter design - one vehicle-side input, two independent outputs
All of our products are engineered and designed right here in Metairie, Louisiana. With over 15 years of experience building lighting for the automotive aftermarket, we control every step of the process - from R&D to final assembly - so you're getting a part built to a standard, not just a spec sheet.
Whether it's an install question, a fitment question, or you just want a second opinion before you order - pick up the phone and talk to someone who actually knows the product. No call centers, no scripts. Just people who know Jeeps, Broncos, Tacomas, and trucks as well as you do.
We don't make one-size-fits-all lighting. Every product is engineered around the specific fitment, electronics, and driving demands of the platform it's built for - so what you install is what was designed for your vehicle from day one.
Before anything ships, it's been run through real-world abuse - mud, vibration, weather, and mileage - not just a bench test. If it can't survive the trail or the daily commute, it doesn't make it to your truck.
We stand behind what we build. Every Oracle product ships with a manufacturer warranty and a team that actually honors it - because a good part with no support isn't a good deal.
Orders ship quickly from our Metairie facility, with tracking sent the moment your parts are on their way - so you know exactly when to expect them, every time.
