I would get any kind of aftermarket tail lights with a clear reverse light lens. That will make a huge difference in the amount of light that the reverse lights put behind you.
If you really want a large amount of light behind you,
these LED reverse lights seem to be popular on here.
I have them on my truck, and several other members here have them.
I was going to go with the LED pods before I got these LED reverse lights.

(They are lighting up the road a good 50 feet down the drive)
I would recommend upgrading those tail light lenses at minimum.
