Trouble with Low Voltage Firefly Magic Firefly Lights?
The below troubleshooting tips will help determine if the lights work properly and are operating as expected.
IMPORTANT: Each "Low Voltage Unit" (see photo below) should be disconnected from any Low Voltage Lighting System and be tested as a standalone unit. Make sure that the disconnected power wires (which are not being used for 12V AC/DC power), are not touching or shorted together.

A). If SOME of the LEDs are working on the Low Voltage Unit: |
1. Visually inspect the black wire from the control box to the LED on all the ‘non-working’ LEDs. ![]() Look for any cuts, nicks, damaged wires, or missing LEDs (see photo). |
2. If any damage or missing LEDs are found, please see our LED / DC Jack Repair Guide (link under construction). |
