Landscape lights not working? A troubleshooting guide
If your landscape lights stopped working, check the basics first: is the transformer getting power and switched on, is the timer or photocell set correctly, and did a breaker or GFCI outlet trip? If only some lights are out, it's usually a bad connection, a failed bulb, or a damaged wire. Whole-system outages almost always trace back to the transformer or its outlet.
Start at the transformer
Most 'all my lights are out' problems are at the transformer: a tripped GFCI outlet, a timer that lost its schedule after a power blip, or a transformer switched off. Reset the outlet and confirm the timer settings first.
If only some lights are out
- A single dark fixture usually means a failed lamp or a loose connector
- A run going dark can indicate a cut or corroded wire
- Dim, flickering lights often point to voltage drop or a wiring fault

Why do my lights come on at the wrong time?
The timer or photocell needs resetting — power outages and seasonal daylight changes commonly throw off the schedule.
Can a single bad bulb take out a whole run?
Usually not with LED, but a bad connection at one fixture can affect others downstream.
