Hi colin&sue
Incorporates light & 2 speed fan & clips onto hockey stick above bed & just plug into existing light. Available on online caravan stores. Good things & you don't need anything better.

The bulb in the fan light is a 12 volt T10 globe. Google this and there will be many different choices. I got mine from my local Jayco dealer, they kept some T10 globes in stock. Hope this helps.
