I ride my bike alot. I have 70,000 miles on my 2008 Ultra-glide. Sometimes I get stuck in bad weather since I live in New England. Well to make a long story short after my last encounter with the weather (torential downpour) I cleaned the bike the next day and notice the radio backlight was out. Everything works fine but no light Is there a light bulb in there somewhere or will my tunes be in the dark forever. Thanks in advance.
