Product Information Upgrades Stock Factory Tail Lights Adds Sequentials to Hazard, Brake, and Lock/Unlock Modes Exceptional Electronics Easy Plug-N-Play Installation Fits All 2010-2023 Mustangs with US Spec Tail Lights Product Description Upgrade Your Factory Mustang Tail Lights with Raxiom's Sequential Tail Light Harness Kit If you're a Mustang owner, you know that the stock Sequential Tail Lights of the 2010-2023 models look great. However, they only sequence when used as turn signals, which can be a minor inconvenience. Fortunately, Raxiom has come up with a solution with their Plug-and-Play Tail Light Sequencer, allowing you to add additional sequential modes. With the Raxiom Sequential Tail Light Harness Kit, you'll get more than just turn signal sequencing. When activated, the turn signals or hazard lights will sequence from the center light outwards and repeat until turned off. Additionally, the tail lights will sequence once when the car is locked/unlocked or when the brakes are applied, then stay lit during braking. The Raxiom Sequential Tail Light Harness Kit is made with state-of-the-art electronic components and features a simple plug-in connector that easily inserts into the stock wiring harness. This kit includes two inline unit harnesses, one for each side, that replace your factory harness. Installation is a breeze with the Raxiom Mustang Sequential Tail Light Harness Kit. It's a direct plug-in replacement for the stock wiring harness, meaning you simply unplug the old harness and plug in the new Raxiom sequential harness in its place. This Raxiom Tail Light Sequencer Harness Kit is designed to fit all 2010 to 2023 Mustangs, including the V6, GT, BOSS, and Shelby GT500 models. However, please note that this product is designed for Mustangs sold in the US and may not function correctly on Mustangs sold in the EU or UK without modifications to the wiring harness.
