I added a lighted trunk handle this week. I really like the LED brake light on it. It adds a lot more light than I would have thought and I think it makes a huge difference in the visibility. I have a hitch on my bike and would like to add a light on it using my plug in for the trailer. I searched on here for some info, but I don't have much luck with the search feature. I'm sure that people here have done this, whether it is a light or lighted mud flap. I would love to see some pictures of things you have done, thanks.
