Used this complete LED tail light kit by Piranha. It is submersible so no additional worries about sealing it.
LED Tail lights
It is a complete kit including a license plate bracket and found it locally at Lowes for $74. Took about 30 minutes to swap out. It really improves the visibility and safety from the back.
I personally like this shape better than the giant bus lights as well. Next time I pull it out of the garage I'll update a photo.
