I got them. Those things are Bright! Install was easy, even for me. They make it kinda tight room-wise where the pin goes, but I was able to get my locking pin to work. The safty chain spots are still usable. They have a 3-way switch on the back of the unit. On, off, and on with back-up lights. If ya wire them straight to the battery, you can have them with the truck off, great for unhooking the trailer or messing with the propane tanks at night. All in all, I like them, especially at night.
