Troubleshooting Outdoor Lighting: Common Issues and Quick Fixes

Outdoor lighting systems are built to last, but over time, small issues can appear that affect performance. At Kings Outdoor Lighting, we’ve seen it all — from flickering path lights to string lights that suddenly stop working. The good news? Many of these problems can be solved with simple troubleshooting steps.

1. Flickering Lights

• Possible Causes: Loose connections, incompatible dimmers, or a failing transformer.

• Quick Fix: Check connections, tighten wire nuts, and confirm your dimmer is LED-compatible.

2. Dead Zones in Landscape Lighting

• Possible Causes: Voltage drop from long wire runs.

• Quick Fix: Shorten runs, use heavier gauge wire, or add a secondary transformer.

3. Power Adapter Failures

• Possible Causes: Overloaded transformer or water ingress.

• Quick Fix: Ensure the adapter wattage matches your load, and check that connections are properly waterproofed.

4. String Light Failures

• Possible Causes: Burned-out bulbs, loose sockets, or damaged wiring.

• Quick Fix: Swap bulbs, inspect sockets, and test with a known-good power supply.
