1. Identify the Type of Running Light:
* Are they integrated into the headlights? Many newer Suburbans have DRLs integrated into the headlights themselves. Replacing these often requires replacing the entire headlight assembly.
* Are they separate lamps? Older models might have separate running light bulbs in the front bumper or grille.
2. Locate the Bulb(s):
* Consult your owner's manual: This is the most crucial step. Your owner's manual will have diagrams showing the location of the bulbs and specific instructions for your Suburban's year and model.
* Visual inspection: Carefully examine the front of your Suburban. If the running lights are separate, you'll likely see access points (usually small covers or screws) near the lights themselves.
3. Access the Bulb(s):
* Remove any covers or trim pieces: This usually involves unscrewing fasteners or carefully prying off plastic clips. Be gentle to avoid breaking anything.
* Disconnect the electrical connector: This is a small connector that plugs into the back of the bulb. Gently unplug it.
4. Replace the Bulb(s):
* Note the type of bulb: Write down the bulb type (e.g., 194, 168, etc.) This is crucial for buying the correct replacement.
* Install the new bulb(s): Carefully insert the new bulbs into their sockets, making sure they are properly seated.
* Reconnect the electrical connector: Plug the connector back into the new bulb.
5. Reassemble:
* Replace any covers or trim pieces: Make sure everything is securely fastened.
Important Considerations:
* Always disconnect the negative terminal of your battery before working on any electrical components. This prevents accidental shorts and electrical shocks.
* Use the correct type of bulb: Using an incorrect bulb can lead to improper function or damage to the electrical system.
* If you're uncomfortable working on your vehicle's electrical system, take it to a qualified mechanic.
