If you’re wondering how to turn on puddle lights for your GMC Sierra, the process is usually straightforward, and it enhances safety and convenience—especially at night or in dimly lit areas. Here’s how to activate them, plus a few troubleshooting tips if they’re not working as expected.How to Turn On Puddle Lights for GMC Sierra1. Unlock with Key Fob: Puddle lights are designed to automatically turn on when you approach your truck and unlock the doors using the key fob. Simply press the “unlock” button, and you should see the lights illuminate beneath the side mirrors or doors.2. Approach Detection (if equipped): Some newer GMC Sierras feature proximity sensors in the keyless entry system. If your truck is equipped, the puddle lights may activate simply by approaching with your key fob on your person.3. Door Open Activation: Opening the door—even from the inside—should activate the puddle lights for extra visibility when stepping out.4. Settings in Infotainment: For models with advanced infotainment systems, you can adjust lighting preferences. Go to your vehicle’s settings > vehicle customization > exterior lighting, and ensure “Approach Lights” or “Puddle Lights” are enabled.Troubleshooting: If your puddle lights aren’t turning on, check that your vehicle isn’t in “theater mode” (which dims onboard lighting after the doors are locked), ensure the bulbs or LEDs aren’t faulty, and double-check settings in the infotainment system. Also, make sure the key fob battery is functional.As a designer, I often consider how ambient lighting like puddle lights not only improves nighttime visibility but also adds a premium feel to your vehicle’s first impression—similar to how accent lighting can elevate a home’s entryway.
