Why Do My Landscape Lights Keep Flickering?

Flickering low-voltage landscape lights can be caused by loose or corroded connections, damaged cable, a failing fixture, transformer issues or voltage problems within the lighting run. The location of the flicker is an important diagnostic clue.

If one fixture flickers

A problem isolated to one light often points toward that fixture, lamp or nearby connection rather than the entire system.

If several lights flicker together

Multiple fixtures changing at the same time can indicate a shared connection, cable run or transformer-side issue. Troubleshooting should follow the shared path instead of replacing every affected fixture.

Intermittent problems matter

Outdoor electrical connections can behave differently when wet, disturbed or under load. A system that works sometimes can still have a connection or cable problem that needs attention.

Repair before replacing everything

Existing systems can often be diagnosed component by component. Fort Mill Irrigation provides landscape lighting troubleshooting and repair for transformers, low-voltage wiring, connections and fixtures.
