One thing to keep in mind. If you did not install the fan originally, look out for the chance that the installer did not connect the blue wire, (light kit power), in the fan canopy as per the instructions. This is a common issue, since the fan will work fine without the blue wire getting power. Once you add a light kit, that blue wire must be spliced in with the black fan power wire inside the ceiling box, or the lights won't work. This is just a heads up in case you install the light kit only to find that the lights won't power up.
