I just got one of these and wasn't expecting it being more than just a hitch plug with a reflector. I knew it was advertised as a brake light and am pleasantly surprised to see that it actually is a nice bright light. Since I don't tow anything, and like to keep things nice and tidy I bought this to cover the opening, for a low price I got a nice looking device that gives me a 4th brake light too. Figured anyone who liked this idea, and a little added safety could check this link out. Less than $13 shipped off ebay.
