We added the light kits to all of the ceiling fans. If you are lucky, the house will have an extra (red) wire to the fan that can be used for the light kit, and the wall switch replaced with either a double switch option (this is what we used), or a fan/light speed /dimmer controller.
If you decide to do this, some words of caution. with the power OFF, remove the round plate at the bottom of the fan (typically 3 screws) and take a look at the connector for the light kit, a photo is a good idea, and use this to get a mating light kit. Take a close look at the light kit, I accidentally bought one that used a very unusual 2 pin twist (G22?) base, and I had a lot of trouble getting replacement bulbs, so I had to convert to standard Edison or candelabra bases. There are also remote control options for fans and lights, but these can be tricky getting the receiver mounted inside the base of the fan.
