* If the lights come with adhesive backing, clean the surface thoroughly and apply the lights according to the manufacturer’s instructions.

**4. Wire the Running Lights:**

* **Identify the Wires:** Most running light kits will have three wires:
* **Positive (+):** Connects to a power source.
* **Negative (-):** Connects to ground.
* **Optional Dimming Wire:** Connects to the headlight circuit to dim the running lights when the headlights are turned on. This wire isn’t always present.
* **Connect the Ground Wire:**
* Find a suitable grounding point on your vehicle’s chassis.
* This is usually a bare metal surface with a bolt or screw.
* Attach the ground wire to the grounding point using a ring terminal and a bolt or screw.
* Ensure the connection is clean and secure.
* **Connect the Positive Wire:** There are several ways to connect the positive wire, depending on how you want the running lights to operate.
* **Ignition-Switched Power:** This is the most common method. The running lights will turn on automatically when the ignition is turned on.
* Locate an ignition-switched power source in your vehicle’s fuse box. Use a multimeter to confirm the circuit is only powered when the ignition is on.
* Use a fuse tap or add-a-circuit connector to tap into the chosen circuit.
* Connect the positive wire of the running lights to the fuse tap.
