Hi

It's a high intensity rear light intended only to be used in fog. It's a European requirement and is pretty effective in a real fog... stands out much better than regular rear lights.

But then morons come along and switch them on at night in the rain where they blind following motorists.

 

Photos of bumper and rear turn-signal lights attached. The smaller dummy hole use to be a smaller turn signal that accompanied a larger signal that was on my bumper. The ones on the bumper got chucked (looked ****ty and kept breaking). Not sure what I'll do with the smaller 2" hole. Maybe I'll look around for a 2" led or something.

As you can see the bumper is a very simple 2x4 steel tube that wraps the corners. It is mounted to the stock mount holes. My truck has a 1.5" body lift also. A large part of the side corner panel was chopped off behind the tires. I thought about adding a 1" tube coming out of the bumper for fastening and climbing....maybe some day.
