I installed a third eye. A third brake light above the rear window. I have had this thing sitting in my cart on Amazon for like a year because I wasn't sure if it would look any good, or whatever. But I was over at Ryan Phelps' house and noticed that he had the exact same one, and it looked OK. So after looking around for any other options, I just went ahead and ordered. I never use the rear washer anyway, so I popped that out, drilled the hole a bit larger, and stuck this thing in. Then tapped it into the brake light at one of the original bullet connections on the LH brake light.
