Lights are flickering

  1. Are the light bulbs in their socket and turned towards the towers?
  2. Are the cords at the bottom of the lights fully inserted?

It is important to make sure that the light bulbs are always turned towards the towers and the cords are fully inserted into the light ballast. If the light bulbs are not properly aligned in the ballast and the cords not fully inserted it could lead to your lights flickering.
