  1. Check the fuse box

    Check the fuse box to make sure one of the circuits hasn't been tripped and there are no blown fuses. If either of these issues is found to be the problem, either reset the circuit breaker, or change the blown fuse.

  2. Check electrical sockets

    Inspect the electrical sockets the lights are plugged into to make sure they are working. Turn off the power to the sockets, and remove the face to make sure it is still connected. If the wires are connected, restore power, and test with a circuit tester.

  3. Check the light fuses

    Look in the compartment near the plug of the lights to determine if there are any blown fuses. If any of the fuses are blown, replace them.

  4. Check each individual light

    If nothing else rectifies the problem, check each individual light for a loose or blown bulb. If you find a loose or blown bulb, either tighten or replace the bulb entirely.
