When your tail light trail guards work to good! Backed into something and the tail light guard worked great at proteching my tail light. But the guards bend my the corner of my cab. So I decided to install some new flush mount 4" LED lights (amazon) and a set of Warroir products S918 powered coated cab corners. I ordered the un-cut corners by mistake so I had to do some cutting for the gas filler and some drilling for the wires. But turned out pretty good I think. Last picture is of the before and after tail lights. I have factory looking LEDs in there in the begining. Round ones are just as bright and don't stick out. I also added backup lights to the bumper.
