I changed out the two single Hanma LED lights, i had mounted under the rear for extra reverse lighting, to two 2x6 Hanma LED lights. This is what the 2x6 flood lights look like (thanks [MENTION=50591]gaterose[/MENTION] for the pic).
Sorry for the crummy phone pics. I have them mounted on both sides of the spare tire. There are already threaded holes in those locations.
Here is night shot with the camera on the ground so you can actually see them.
This shot is from a normal level. From this level it almost looks like the high powered LED bulbs in my tail light housings are throwing out all that light.
One of the main thing i like about these lights are that you really don't see them until i put the truck in reverse.
