I used the factory Ford type cab lights from a SuperDuty but ended up putting on smoked lenses which went well with the black truck. If you want LED and to look somewhat like factory, Grote makes some nice heavy duty models that are for school buses that looks very similar to the factory Ford lights. I have installed them on a few super duty trucks.

Here are a few pictures. The install was somewhat of a pain compared to other trucks because of some extra metal pieces in that area of the truck under the headliner. I used the lights with the studs, and if I did it again, would go with screws from the top, even though those are not my preferred way, but would have saved a ton of time.
