The light kit was tested before it was shipped but it might have been damaged in transit.
Please check that the outlet is energized (plug in a different light or appliance).
Check that the transformer is plugged in.
Test the extension cord. Take the extension cord out of the circuit by plugging the transformer cord directly to the remote controller in the light kit.
Check that the connection between the 12' extension and the power supply is firmly connected (plugged in together).
Press the remote control (+) switch to confirm that the remote activates the LED light string. Confirm the light intensity controller is on and functional (See instructions included with the the light kit).
Pull the cord between your thumb and forefinger under light pressure to explore for damage to either the transformer cord and the extension cord. Rough sections could reveal a damaged cord. We can replace either cord.
If the lights still won't come on you probably have a damaged transformer or extension. Upon receipt of shipping confirmation with UPS we will send you a replacement light kit.
