Troubleshooting Guide: Why Your In Ground Well Lights Might Not Be Working
In ground well lights offer a clean, seamless look for landscape illumination, perfect for highlighting trees, pathways, and architectural features. However, like any outdoor lighting, they can occasionally stop working—and the cause isn’t always obvious.
This practical guide helps you identify and resolve the most common issues, so your landscape can shine again in no time.
Check the Obvious: Power Supply & Connections
Start with the basics. If all your in ground well lights have gone dark, it’s likely a power issue. Make sure:
-
The transformer is plugged in and switched on.
-
The circuit breaker or GFCI outlet hasn’t tripped.
-
Your timer or smart controller is working correctly.
💡 Tip: For 12V low voltage lighting, ensure the transformer is compatible and functioning. Explore Gardenreet's low-voltage transformers for reliable options.
Inspect the Bulb and Socket
If only one fixture isn’t lighting up, the issue might be with the bulb or socket. Open the housing and check:
-
Is the bulb burned out or loose?
-
Is the socket corroded or filled with debris?
-
Are there signs of moisture?
Replacing the bulb is a quick fix. If corrosion is present, clean the socket or replace the entire fixture if necessary.
Look for Cut or Damaged Wires
Outdoor conditions can lead to cut or frayed wires, especially if recent digging, landscaping, or heavy rain occurred.
-
Use a voltage tester to check continuity.
-
Look for animal damage or sharp bends in the cable.
-
Make sure waterproof wire connectors were used.
Water intrusion and loose connections are common culprits in underground lighting failure.
Drainage and Waterproofing Failures
If your in ground lights are filled with water, the seal may have failed. Over time, even IP65/IP67-rated fixtures can wear down.
To prevent this:
-
Ensure proper drainage under each fixture.
-
Check the gasket seal and housing integrity regularly.
-
Consider elevating the fixture slightly with gravel or drainage base.

Burned-Out Transformer or Overloaded Circuit
Too many lights on one transformer can overload the circuit, especially if your system wasn’t planned with total wattage in mind.
-
Add up the total wattage of your lights.
-
Make sure the transformer’s capacity is at least 20% above that.
-
Use multiple circuits or transformers for larger installations.

When to Call a Professional
Some issues, such as deep electrical faults or flooded underground wiring, require a professional electrician or lighting technician. If your lights fail repeatedly even after basic troubleshooting, don’t risk safety—get expert help.
FAQ
Q1: Why is my in ground light not working even after I replaced the bulb?
Check the socket for corrosion or debris. Also, test the voltage at the fixture—if power isn’t reaching it, the issue might be upstream (e.g., wiring or transformer).
Q2: Can I waterproof my in ground lights myself?
Yes, but it depends on the design. You can reseal gaskets or add extra silicone, but if the fixture housing is compromised, replacement is the safer option.
Q3: How often should I check my in ground lights?
Inspect your system seasonally, especially after winter or heavy storms. Regular checks can prevent small issues from becoming expensive repairs.
Conclusion
Troubleshooting in ground well lights doesn’t have to be complicated. With regular checks and quality components, like those from Gardenreet, you can keep your landscape lighting reliable and glowing beautifully year-round.
